A disability is any condition that makes it more difficult for a person to do certain activities or interact with the world around them. These conditions, or impairments, may be cognitive, developmental, intellectual, mental, physical, sensory, or a combination of multiple factors. Impairments causing disability may be present from birth or occur during a person's lifetime. The World Health Organization proposes the following definition of disabilities:
"Disabilities is an umbrella term, covering impairments, activity limitations, and participation restrictions. An impairment is a problem in body function or structure; an activity limitation is a difficulty encountered by an individual in executing a task or action; while a participation restriction is a problem experienced by an individual in involvement in life situations. Disability is thus not just a health problem. It is a complex phenomenon, reflecting the interaction between features of a person's body and features of the society in which he or she lives."
Disability is a contested concept, with different meanings in different communities. The term disability may refer to physical or mental attributes that some institutions, particularly medicine, view as needing to be fixed (the medical model); it may also refer to limitations imposed on people by the constraints of an ableist society (the social model); or the term may serve to refer to the identity of disabled people. Physiological functional capacity (PFC) is a measure of an individual's performance level that gauges one's ability to perform the physical tasks of daily life and the ease with which these tasks are performed. PFC declines with advancing age to result in frailty, cognitive disorders, or physical disorders, all of which may lead to labeling individuals as disabled. According to the World Report on Disability, 15% of the world's population or 1 billion people are affected by disability. 
There are many different causes of disability that often affect basic activities of daily living, such as eating, dressing, transferring, and maintaining personal hygiene; or advanced activities of daily living such as shopping, food preparation, driving, or working.
For the purposes of the Americans with Disabilities Act of 1990, the US Equal Employment Opportunity Commission regulations provide a list of conditions that should easily be concluded to be disabilities: deafness, blindness, an intellectual disability (formerly termed mental retardation), partially or completely missing limbs or mobility impairments requiring the use of a wheelchair, autism, cancer, cerebral palsy, diabetes, epilepsy, HIV/AIDS, multiple sclerosis, muscular dystrophy, major depressive disorder, bipolar disorder, post-traumatic stress disorder, obsessive compulsive disorder, and schizophrenia.
This is not an exhaustive list and many injuries and medical problems cause disability. Some causes of disability, such as injuries, may resolve over time and are considered temporary disabilities. An acquired disability is the result of impairments that occur suddenly or chronically during the lifespan, as opposed to being born with the impairment. Invisible disabilities may not be obviously noticeable.
Contemporary understandings of disability derive from concepts that arose during the West's scientific Enlightenment; prior to the Enlightenment, physical differences were viewed through a different lens.
There is evidence of humans during prehistory that looked after people with disabilities. At the Windover Archeological Site, one of the skeletons that was found was a male about 15 years old, who had spina bifida. The condition meant that the boy, probably paralyzed below the waist, was taken care of in a Hunter-gatherer community.
Provision that enabled individuals with impaired mobility to access temples and healing sanctuaries were made in ancient Greece..Specifically, by 370 B.C., at the most important healing sanctuary in the wider area, the Sanctuary of Asclepius at Epidaurus, there were at least 11 permanent stone ramps that provided access to mobility-impaired visitors to nine different structures; evidence that people with disabilities were acknowledged and cared for, at least partly, in ancient Greece.
During the Middle Ages, madness and other conditions were thought to be caused by demons. They were also thought to be part of the natural order, especially during and in the fallout of the Plague, which wrought impairments throughout the general population. In the early modern period there was a shift to seeking biological causes for physical and mental differences, as well as heightened interest in demarcating categories: for example, Ambroise Pare, in the sixteenth century, wrote of "monsters", "prodigies", and "the maimed". The European Enlightenment's emphases on knowledge derived from reason and on the value of natural science to human progress helped spawn the birth of institutions and associated knowledge systems that observed and categorized human beings; among these, the ones significant to the development of today's concepts of disability were asylums, clinics, and, prisons.
Contemporary concepts of disability are rooted in eighteenth- and nineteenth-century developments. Foremost among these was the development of clinical medical discourse, which made the human body visible as a thing to be manipulated, studied, and transformed. These worked in tandem with scientific discourses that sought to classify and categorize and, in so doing, became methods of normalization.
The concept of the "norm" developed in this time period, and is signaled in the work of the Belgian statistician, sociologist, mathematician, and astronomer Adolphe Quetelet, who wrote in the 1830s of l'homme moyen - the average man. Quetelet postulated that one could take the sum of all people's attributes in a given population (such as their height or weight) and find their average and that this figure should serve as a norm toward which all should aspire.
This idea of statistical norm threads through the rapid take-up of statistics gathering by Britain, the United States, and the Western European states during this time period, and it is tied to the rise of eugenics. Disability, as well as other concepts including: abnormal, non-normal, and normalcy came from this. The circulation of these concepts is evident in the popularity of the freak show, where showmen profited from exhibiting people who deviated from those norms.
With the rise of eugenics in the latter part of the nineteenth century, such deviations were viewed as dangerous to the health of entire populations. With disability viewed as part of a person's biological make-up and thus their genetic inheritance, scientists turned their attention to notions of weeding such as "deviations" out of the gene pool. Various metrics for assessing a person's genetic fitness, which was then used to deport, sterilize, or institutionalize those deemed unfit. At the end of the Second World War, with the example of Nazi eugenics, eugenics faded from public discourse, and increasingly disability cohered into a set of attributes that medicine could attend to - whether through augmentation, rehabilitation, or treatment. In both contemporary and modern history, disability was often viewed as a by-product of incest between first-degree relatives or second-degree relatives.
In the early 1970s, disability activists began to challenge how society treated disabled people and the medical approach to disability. Due to this work, physical barriers to access were identified. These conditions functionally disabled them, and what is now known as the social model of disability emerged. Coined by Mike Oliver in 1983, this phrase distinguishes between the medical model of disability - under which an impairment needs to be fixed - and the social model of disability - under which the society that limits a person needs to be fixed.
People-first language is one way to talk about disability that some people prefer. Many others prefer identity-first language. Using people-first language is said to put the person before the disability, so those individuals who prefer people-first language, prefer to be called, "a person with a disability". This style is reflected in major legislation on disability rights, including the Americans with Disabilities Act and the UN Convention on the Rights of Persons with Disabilities.
"The American Psychological Association style guide states that, when identifying a person with a disability, the person's name or pronoun should come first, and descriptions of the disability should be used so that the disability is identified, but is not modifying the person. Acceptable examples included "a woman with Down syndrome" or "a man who has schizophrenia". It also states that a person's adaptive equipment should be described functionally as something that assists a person, not as something that limits a person, for example, "a woman who uses a wheelchair" rather than "a woman in/confined to a wheelchair".
A similar kind of "people-first" terminology is also used in the UK, but more often in the form "people with impairments" (such as "people with visual impairments"). However, in the UK, identity-first language is generally preferred over people-first language.
The use of "people-first" terminology has given rise to the use of the acronym PWD to refer to person(s) (or people) with disabilities (or disability). However other individuals and groups prefer identity-first language to emphasize how a disability can impact people's identities. Which style of language used varies between different countries, groups and individuals.
In contrast to people-first language, identity-first language describes the person as "disabled". Some people prefer this and argue that this fits the social model even better than does people-first language, as it emphasizes that the person is disabled not by their body, but by a world that does not accommodate them.
This is especially true in the UK, where it is argued under the social model that while someone's impairment (for example, having a spinal cord injury) is an individual property, "disability" is something created by external societal factors such as a lack of accessibility. This distinction between the individual property of impairment and the social property of disability is central to the social model. The term "disabled people" as a political construction is also widely used by international organizations of disabled people, such as Disabled Peoples' International (DPI).
Using the identity-first language also parallels how people talk about other aspects of identity and diversity. For example:
"In the autism community, many self-advocates and their allies prefer terminology such as 'Autistic,' 'Autistic person,' or 'Autistic individual' because we understand autism as an inherent part of an individual's identity -- the same way one refers to 'Muslims,' 'African-Americans,' 'Lesbian/Gay/Bisexual/Transgender/Queer,' 'Chinese,' 'gifted,' 'athletic,' or 'Jewish.'"
Similarly, the Deaf community rejects people-first language in favor of identity-first language.
To a certain degree, physical impairments and changing mental states are almost ubiquitously experienced by people as they age. Aging populations are often stigmatized for having a high prevalence of disability. Kathleen Woodward, writing in Key Words for Disability Studies, explains the phenomenon as follows:
Aging is invoked rhetorically - at times ominously - as a pressing reason why disability should be of crucial interest to all of us (we are all getting older, we will all be disabled eventually), thereby inadvertently reinforcing the damaging and dominant stereotype of aging as solely an experience of decline and deterioration. But little attention has been given to the imbrication of aging and disability.
Studies have illustrated a correlation between disability and poverty. Notably, jobs offered to disabled people are scarce. In the developed world there are programs in place that aid intellectually disabled (ID) people to acquire skills they need in the workforce. Such programs include sheltered workshops and adult day care programs. Sheltered programs consist of daytime activities such as gardening, manufacturing, and assembling. These activities facilitate routine-oriented tasks that in turn allow intellectually disabled people to gain experience before entering the workforce. Similarly, adult day care programs also include day time activities. However, these activities are based in an educational environment where intellectually disabled are able to engage in educational, physical, and communication-based tasks. This educationally based environment helps facilitate communication, memory, and general living skills. In addition, adult day care programs arrange opportunities for their students to engage in community activities. Such opportunities are arranged by scheduling field trips to public places (e.g. Disneyland, Zoo, and Movie Theater). Despite, both programs providing essential skills for intellectually disabled prior to entering the workforce researchers have found that intellectually disabled people prefer to be involved with community-integrated employment. Community-integrated employment are job opportunities offered to intellectually disabled people at minimum wage or a higher rate depending on the position. Community-integrated employment comes in a variety of occupations ranging from customer service, clerical, janitorial, hospitality and manufacturing positions. Within their daily tasks, community-integrated employees work alongside employees who do not have disabilities, but who are able to assist them with training. All three options allow intellectually disabled people to develop and exercise social skills that are vital to everyday life. However, it is not guaranteed that community-integrated employees receive the same treatment as employees that do not have ID. According to Lindstrom, Hirano, McCarthy, and Alverson, community-integrated employees are less likely to receive raises. In addition, studies conducted in 2013 illustrated only 26% of employees with ID retained full-time status.
Furthermore, many with disabilities, intellectual and (or) psychical, finding a stable workforce poses many challenges. According to a study conducted by JARID (Journal of Applied Research and Intellectual Disability, indicates that although finding a job may be difficult for an intellectually disabled individual, stabilizing a job is even harder. This is largely due to two main factors: production skills and effective social skills. This idea is supported by Chadsey-Rusch, who claims that securing employment for the intellectually disabled, requires adequate production skills and effective social skills. However, other underlying factors for job loss include, structural factors and the integration between worker and workplace. As stated by Kilsby, limited structural factors can affect a multitude of factors in a job. Factors such as a restricted number of hours an intellectually disabled person is allowed to work. This in return, according to Fabian, Wistow, and Schneider leads to a lack of opportunity to develop relationships with coworkers and a chance to better integrate within the workplace. Nevertheless, those who are unable to stabilize a job often are left discouraged. According to the same study conducted by JARED, many who had participated found that they had made smaller incomes when compared to their co-workers, had an excess of time throughout their days, because they did not have work. They also had feelings of hopelessness and failure. According to the NOD ( National Organization On Disability), not only do the (ID) face constant discouragement but many live below the poverty line, because they are unable to find or stabilize employment and (or) because of employee restricting factors placed on ID workers. This then causes the (ID) the incapacity to provide for themselves basic necessities one needs. Items such as food, medical care, transportation, and housing.
There is a global correlation between disability and poverty, produced by a variety of factors. Poverty and disability go hand in hand. The poverty rate for working-age people with disabilities is nearly two and a half times higher than that for people without disabilities. Disability and poverty may form a vicious circle, in which physical barriers and stigma of disability make it more difficult to get income, which in turn diminishes access to health care and other necessities for a healthy life. In societies without state funded health and social services, living with a disability could require spending on medication and frequent health care visits, in-home personal assistance, and adaptive devices and clothing, along with the usual costs of living. The World report on disability indicates that half of all disabled people cannot afford health care, compared to a third of abled people. In countries without public services for adults with disabilities, their families may be impoverished.
There is limited research knowledge, but many anecdotal reports, on what happens when disasters impact disabled people. Individuals with disabilities are greatly affected by disasters. Those with physical disabilities can be at risk when evacuating if assistance is not available. Individuals with cognitive impairments may struggle with understanding instructions that must be followed in the event a disaster occurs. All of these factors can increase the degree of variation of risk in disaster situations with disabled individuals.
Research studies have consistently found discrimination against individuals with disabilities during all phases of a disaster cycle. The most common limitation is that people cannot physically access buildings or transportation, as well as access disaster-related services. The exclusion of these individuals is caused in part by the lack of disability-related training provided to emergency planners and disaster relief personnel.
The International Classification of Functioning, Disability and Health (ICF), produced by the World Health Organization, distinguishes between body functions (physiological or psychological, such as vision) and body structures (anatomical parts, such as the eye and related structures). Impairment in bodily structure or function is defined as involving an anomaly, defect, loss or other significant deviation from certain generally accepted population standards, which may fluctuate over time. Activity is defined as the execution of a task or action. The ICF lists 9 broad domains of functioning which can be affected:
In concert with disability scholars, the introduction to the ICF states that a variety of conceptual models have been proposed to understand and explain disability and functioning, which it seeks to integrate. These models include the following:
The medical model views disability as a problem of the person, directly caused by disease, trauma, or other health conditions which therefore requires sustained medical care in the form of individual treatment by professionals. In the medical model, management of the disability is aimed at a "cure", or the individual's adjustment and behavioral change that would lead to an "almost-cure" or effective cure. In the medical model, medical care is viewed as the main issue, and at the political level, the principal response is that of modifying or reforming healthcare policy.
The social model of disability sees "disability" as a socially created problem and a matter of the full integration of individuals into society. In this model, disability is not an attribute of an individual, but rather a complex collection of conditions, created by the social environment. The management of the problem requires social action and it is the collective responsibility of society to create a society in which limitations for disabled people are minimal. Disability is both cultural and ideological in creation. According to the social model, equal access for someone with an impairment/disability is a human rights concern. The social model of disability has come under criticism. While recognizing the importance played by the social model in stressing the responsibility of society, scholars, including Tom Shakespeare, point out the limits of the model and urge the need for a new model that will overcome the "medical vs. social" dichotomy. The limitations of this model mean that often the vital services and information persons with disabilities face are simply not available, often due to limited economic returns in supporting them.
The social construction of disability is the idea that disability is constructed by social expectations and institutions rather than biological differences. Highlighting the ways society and institutions construct disability is one of the main focuses of this idea. In the same way that race and gender are not biologically fixed, neither is disability.
Around the early 1970s, sociologists, notably Eliot Friedson, began to argue that labeling theory and social deviance could be applied to disability studies. This led to the creation of the social construction of disability theory. The social construction of disability is the idea that disability is constructed as the social response to a deviance from the norm. The medical industry is the creator of the ill and disabled social role. Medical professionals and institutions, who wield expertise over health, have the ability to define health and physical and mental norms. When an individual has a feature that creates an impairment, restriction, or limitation from reaching the social definition of health, the individual is labeled as disabled. Under this idea, disability is not defined by the physical features of the body but by a deviance from the social convention of health.
The social construction of disability would argue that the medical model of disability's view that a disability is an impairment, restriction, or limitation is wrong. Instead what is seen as a disability is just a difference in the individual from what is considered "normal" in society.
In contexts where their differences are visible, persons with disabilities often face stigma. People frequently react to disabled presence with fear, pity, patronization, intrusive gazes, revulsion, or disregard. These reactions can, and often do, exclude persons with disabilities from accessing social spaces along with the benefits and resources these spaces provide. Disabled writer/researcher Jenny Morris describes how stigma functions to marginalize persons with disabilities:
"Going out in public so often takes courage. How many of us find that we can't dredge up the strength to do it day after day, week after week, year after year, a lifetime of rejection and revulsion? It is not only physical limitations that restrict us to our homes and those whom we know. It is the knowledge that each entry into the public world will be dominated by stares, by condescension, by pity, and by hostility."
Additionally, facing stigma can cause harm to the psycho-emotional well-being of the person being stigmatized. One of the ways in which the psycho-emotional health of persons with disabilities is adversely affected is through the internalization of the oppression they experience, which can lead to feeling that they are weak, crazy, worthless or any number of other negative attributes that may be associated with their conditions. Internalization of oppression damages the self-esteem of the person affected and shapes their behaviors in ways that are compliant with nondisabled dominance. Ableist ideas are frequently internalized when disabled people are pressured by the people and institutions around them to hide and downplay their disabled difference, or, "pass". According to writer Simi Linton, the act of passing takes a deep emotional toll by causing disabled individuals to experience loss of community, anxiety and self-doubt. The media play a significant role in creating and reinforcing stigma associated with disability. Media portrayals of disability usually cast disabled presence as necessarily marginal within society at large. These portrayals simultaneously reflect and influence the popular perception of disabled difference.
There are distinct tactics that the media frequently employ in representing disabled presence. These common ways of framing disability are heavily criticized for being dehumanizing and failing to place importance on the perspectives of persons with disabilities.
Inspiration porn refers to portrayals of persons with disabilities in which they are presented as being inspiring simply because the person has a disability. These portrayals are criticized because they are created with the intent of making non-disabled viewers feel better about themselves in comparison to the individual portrayed. Rather than recognizing the humanity of persons with disabilities, inspiration porn turns them into objects of inspiration for a non-disabled audience.
The supercrip trope refers to instances when media reports on or portray a disabled person who has made a noteworthy achievement; but center on their disability rather than what they actually did. They are portrayed as awe-inspiring for being exceptional compared to others with the same or similar conditions. This trope is widely used in reporting on disabled athletes as well as in portrayals of autistic savants.
Many disabled people denounce these representations as reducing people to their condition rather than viewing them as full people. Furthermore, supercrip portrayals are criticized for creating the unrealistic expectation that disability should be accompanied by some type of special talent, genius, or insight.
Characters in fiction that bear physical or mental markers of difference from perceived societal norms are frequently positioned as villains within a text. Lindsey Row-Heyveld notes, for instance, "that villainous pirates are scraggly, wizened, and inevitably kitted out with a peg leg, eye patch, or hook hand whereas heroic pirates look like Johnny Depp's Jack Sparrow." Disabled people's visible differences from the abled majority are meant to evoke fear in audiences that can perpetuate the mindset of disabled people being a threat to individual or public interests and well-being.
Some disabled people have attempted to resist marginalization through the use of the social model in opposition to the medical model; with the aim of shifting criticism away from their bodies and impairments and towards the social institutions that oppress them relative to their abled peers. Disability activism that demands many grievances be addressed, such as lack of accessibility, poor representation in media, general disrespect, and lack of recognition, originates from a social model framework.
Embracing disability as a positive identity by becoming involved in disabled communities and participating in disabled culture can be an effective way to combat internalised prejudice; and can challenge dominant narratives about disability.
This section needs expansion. You can help by adding to it. (February 2018)
The experiences that disabled people have to navigate social institutions vary greatly as a function of what other social categories they may belong to. The categories that intersect with a disability to create unique experiences of ableism include, but are not limited to, race and gender. The United Nations Convention on the Rights of Persons with Disabilities differentiates two kinds of disability intersection, race disability intersection and gender disability intersection.
Incidence of disability is reported to be greater among several minority communities across the globe, according to a systematic analysis of the Global Burden of Disease Study. Disabled people who are also racial minorities generally have less access to support and are more vulnerable to violent discrimination.  A study in the journal Child Development indicated that minority disabled children are more likely to receive punitive discipline in low and middle income countries. With respect to disability in the United States, Camille A. Nelson, writing for the Berkeley Journal of Criminal Law, notes the dual discrimination that racial minorities with disabilities experience from the criminal justice system, expressing that for "people who are negatively racialized, that is people who are perceived as being non-white, and for whom mental illness is either known or assumed, interaction with police is precarious and potentially dangerous." 
The marginalization of disabled people can leave persons with disabilities unable to actualize what society expects of gendered existence. This lack of recognition for their gender identity can leave persons with disabilities with feelings of inadequacy. Thomas J. Gerschick of Illinois State University describes why this denial of gendered identity occurs:
"Bodies operate socially as canvases on which gender is displayed and kinesthetically as the mechanisms by which it is physically enacted. Thus, the bodies of disabled people make them vulnerable to being denied recognition as women and men."
To the extent that women and men with disabilities are gendered, the interactions of these two identities lead to different experiences. Disabled women face a sort of "double stigmatization" in which their membership to both of these marginalized categories simultaneously exacerbates the negative stereotypes associated with each as they are ascribed to them. According to The UN Woman Watch, "Persistence of certain cultural, legal and institutional barriers makes women and girls with disabilities the victims of two-fold discrimination: as women and as persons with disabilities." As Rosemarie Garland-Thomson puts it, "Women with disabilities, even more intensely than women in general, have been cast in the collective cultural imagination as inferior, lacking, excessive, incapable, unfit, and useless."
Assistive Technology is a generic term for devices and modifications (for a person or within a society) that help overcome or remove a disability. The first recorded example of the use of a prosthesis dates to at least 1800 BC. The wheelchair dates from the 17th century. The curb cut is a related structural innovation. Other examples are standing frames, text telephones, accessible keyboards, large print, Braille, & speech recognition software. Disabled people often develop personal or community adaptations, such as strategies to suppress tics in public (for example in Tourette's syndrome), or sign language in deaf communities.
As the personal computer has become more ubiquitous, various organizations have formed to develop software and hardware to make computers more accessible for disabled people. Some software and hardware, such as Voice Finger, Freedom Scientific's JAWS, the Free and Open Source alternative Orca etc. have been specifically designed for disabled people while other software and hardware, such as Nuance's Dragon NaturallySpeaking, were not developed specifically for disabled people, but can be used to increase accessibility. The LOMAK keyboard was designed in New Zealand specifically for persons with disabilities. The World Wide Web consortium recognized a need for International Standards for Web Accessibility for persons with disabilities and created the Web Accessibility Initiative (WAI). As at Dec 2012 the standard is WCAG 2.0 (WCAG = Web Content Accessibility Guidelines).
The Paralympic Games (meaning "alongside the Olympics") are held after the (Summer and Winter) Olympics. The Paralympic Games include athletes with a wide range of physical disabilities. In member countries, organizations exist to organize competition in the Paralympic sports on levels ranging from recreational to elite (for example, Disabled Sports USA and BlazeSports America in the United States).
The Paralympics developed from a rehabilitation program for British war veterans with spinal injuries. In 1948, Sir Ludwig Guttman, a neurologist working with World War II veterans with spinal injuries at Stoke Mandeville Hospital in Aylesbury in the UK, began using sport as part of the rehabilitation programs of his patients.
The disability rights movement aims to secure equal opportunities and equal rights for disabled people. The specific goals and demands of the movement are accessibility and safety in transportation, architecture, and the physical environment; equal opportunities in independent living, employment, education, and housing; and freedom from abuse, neglect, and violations of patients' rights. Effective civil rights legislation is sought to secure these opportunities and rights.
The early disability rights movement was dominated by the medical model of disability, where emphasis was placed on curing or treating disabled people so that they would adhere to the social norm, but starting in the 1960s, rights groups began shifting to the social model of disability, where disability is interpreted as an issue of discrimination, thereby paving the way for rights groups to achieve equality through legal means.
On December 13, 2006, the United Nations formally agreed on the Convention on the Rights of Persons with Disabilities, the first human rights treaty of the 21st century, to protect and enhance the rights and opportunities of the world's estimated 650 million disabled people. As of April 2011 , 99 of the 147 signatories had ratified the Convention. Countries that sign the convention are required to adopt national laws, and remove old ones, so that persons with disabilities will, for example, have equal rights to education, employment, and cultural life; to the right to own and inherit property; to not be discriminated against in marriage, etc.; and to not be unwilling subjects in medical experiments. UN officials, including the High Commissioner for Human Rights, have characterized the bill as representing a paradigm shift in attitudes toward a more rights-based view of disability in line with the social model.
In 1976, the United Nations began planning for its International Year of Disabled Persons (1981), later renamed the International Year of Disabled Persons. The UN Decade of Disabled Persons (1983-1993) featured a World Programme of Action Concerning Disabled Persons. In 1979, Frank Bowe was the only person with a disability representing any country in the planning of IYDP-1981. Today, many countries have named representatives who are themselves individuals with disabilities. The decade was closed in an address before the General Assembly by Robert Davila. Both Bowe and Davila are deaf. In 1984, UNESCO accepted sign language for use in the education of deaf children and youth.
In the United States, the Department of Labor's 2014 rules for federal contractors, defined as companies that make more than $50,000/year from the federal government, required them to have as a goal that 7% of their workforce must be disabled people. In schools, the ADA says that all classrooms must be wheelchair accessible. The U.S. Architectural and Transportation Barriers Compliance Board, commonly known as the Access Board, created the Rehabilitation Act of 1973 to help offer guidelines for transportation and accessibility for the physically disabled.
About 12.6% of the U.S. population are individuals who have a mental or physical disability. Many are unemployed because of prejudiced assumptions that a person with disabilities is unable to complete tasks that are commonly required in the workforce. This became a major Human rights issue because of the discrimination that this group faced when trying to apply for jobs in the U.S. Many advocacy groups protested against such discrimination, asking the federal government to implement laws and policies that would help individuals with disabilities.
The Rehabilitation Act of 1973 was enacted with the purpose of protecting individuals with disabilities from prejudicial treatment by government-funded programs, employers, and agencies. The Rehabilitation Act of 1973 has not only helped protect U.S. citizens from being discriminated against but it has also created confidence amongst individuals to feel more comfortable with their disability. There are many sections within The Rehabilitation Act of 1973, that contains detailed information about what is covered in this policy.
On June 22, 1999, the United States Supreme Court issued a ruling in Olmstead vs. L. C. that said unjustified segregation of persons with disabilities constitutes discrimination in violation of title II of the Americans with Disabilities Act. This has been interpreted as meaning people with disabilities must be given all opportunities by the government to stay in their own homes as opposed to assisted living, nursing homes or worse, institutions for the disabled. It has been interpreted as meaning the government must make all reasonable efforts to allow people with disabilities to be included in their respective communities and enjoy family and friends, work if possible, get married, own homes and interact with nondisabled people. This is why the United States has so many community-based services today for the disabled including but not limited to home health aides, personal care attendants and other programs to keep people with disabilities in their own homes and communities.
The federal government enacted The Americans with Disabilities Act of 1990, which was created to allow equal opportunity for jobs, access to private and government-funded facilities, and transportation for disabled people. This act was created with the purpose to ensure that employers would not discriminate against any individual despite their disability. In 1990, data was gathered to show the percentage of disabled people who worked in the U.S. Out of the 13% who filled out the survey, only 53% percent of individuals with disabilities worked while 90% of this group population did not, the government wanted to change this, they wanted Americans with disabilities to have the same opportunities as those who did not have a disability. The ADA required corporations to not only hire qualified disabled people but also accommodate them and their needs.
In the UK, the Department for Work and Pension is a government department responsible for promoting disability awareness and among its aims is to increase the understanding of disability and removal of barriers for disabled people in the workplace. According to a news report, a people survey conducted in the UK shows a 23% increase in reported discrimination and harassment in the workplace at The Department for Work and Pension. The survey shows the number of reports for discrimination due to disability was in the majority compared to discrimination due to gender, ethnicity or age. DWP received criticism for the survey results. As a department responsible for tackling discrimination at work, the DWP results may indicate room for improvement from within. A DWP spokesperson said the survey results do not necessarily indicate an increase in the number of reports, but rather reflecting the outcomes of efforts to encourage people to come forward.
Political rights, social inclusion and citizenship have come to the fore in developed and some developing countries. The debate has moved beyond a concern about the perceived cost of maintaining dependent disabled people to finding effective ways to ensure that disabled people can participate in and contribute to society in all spheres of life.
In developing nations, where the vast bulk of the estimated 650 million disabled people reside, a great deal of work is needed to address concerns ranging from accessibility and education to self-empowerment, self-supporting employment, and beyond.
In the past few years, disability rights activists have focused on obtaining full citizenship for the disabled.
There are obstacles in some countries in getting full employment; public perception of disabled people may vary.
Disability abuse happens when a person is abused physically, financially, verbally or mentally due to the person having a disability. As many disabilities are not visible (for example, asthma, learning disabilities) some abusers cannot rationalize the non-physical disability with a need for understanding, support, and so on.
As the prevalence of disability and the cost of supporting disability increases with medical advancement and longevity in general, this aspect of society becomes of greater political importance. How political parties treat their disabled constituents may become a measure of a political party's understanding of disability, particularly in the social model of disability.
Disability benefit, or disability pension, is a major kind of disability insurance that is provided by government agencies to people who are temporarily or permanently unable to work due to a disability. In the U.S., the disability benefit is provided in the category of Supplemental Security Income. In Canada, it is within the Canada Pension Plan. In other countries, disability benefits may be provided under social security systems.
Costs of disability pensions are steadily growing in Western countries, mainly in Europe and the United States. It was reported that, in the UK, expenditure on disability pensions accounted for 0.9% of gross domestic product (GDP) in 1980; two decades later it had reached 2.6% of GDP. Several studies have reported a link between increased absence from work due to sickness and elevated risk of future disability pension.
A study by researchers in Denmark suggests that information on self-reported days of absence due to sickness can be used to effectively identify future potential groups for disability pension. These studies may provide useful information for policymakers, case managing authorities, employers, and physicians.
In Switzerland, social policies in the field of disability have been significantly reshaped over the last two decades by reducing the number of allowances awarded and by increasing the recourse to vocational rehabilitation measures. Drawing on interviews conducted with individuals who have been involved in programmes set up by Swiss disability insurance, a study highlights their uncertainties and concerns relating to their place in society, as well as their reactions to disability insurance's interventions.
Private, for-profit disability insurance plays a role in providing incomes to disabled people, but the nationalized programs are the safety net that catch most claimants.
Estimates of worldwide and country-wide numbers of individuals with disabilities are problematic. The varying approaches taken to defining disability notwithstanding, demographers agree that the world population of individuals with disabilities is very large. For example, in 2012, the World Health Organization estimated a world population of 6.5 billion people. Of those, nearly 650 million people, or 10%, were estimated to be moderately or severely disabled. In 2018 the International Labour Organization estimated that about a billion people, one-seventh of the world population, had disabilities, 80% of them in developing countries, and 80% of working age. Excluding disabled people from the workforce was reckoned to cost up to 7% of gross domestic product.
Disability is more common in developing than in developed nations. The connection between disability and poverty is thought to be part of a "vicious cycle" in which these constructs are mutually reinforcing.
