It includes parts of both the U.S. states of Missouri and Illinois. The city core is on the Mississippi Riverfront on the border with Illinois in the geographic center of the metro area. The Mississippi River bisects the metro area in half geographically between Illinois and Missouri; however, the Missouri half is much more populous. St. Louis is the largest metro area in Missouri and the second largest in Illinois. St. Louis County is independent of the City of St. Louis and their two populations are generally tabulated separately.
St. Louis, MO-IL (MSA)--and the focus of this page--includes the City of St. Louis; the metropolitan statistical area Illinois counties of Bond, Calhoun, Clinton, Jersey, Macoupin, Madison, Monroe, and St. Clair (known collectively as the ); and the Metro East Missouri counties of Franklin, Jefferson, Lincoln, St. Charles, St. Louis County (separate from and not inclusive of the city of St. Louis), and Warren.  
St. Louis-St. Charles-Farmington, MO-IL (CSA) includes all of the aforementioned MSA, plus the combined statistical area Farmington, MO micropolitan statistical area, which includes all of St. Francois County, Missouri, and the Centralia, IL micropolitan statistical area, which includes Marion County, Illinois.
As of 2017 data, the MSA is the
21st-largest in the country that year with a population of 2,807,338; however, the CSA is the  19th-largest in the United States, with a population of 2,911,945. Due to nearly zero growth in St. Louis paired with rapid growth in the Sun Belt and Florida, the St. Louis MSA fell out of the Top 20 Largest MSAs in the United States in 2017 for the first time since 1840.   
As of 2018, Greater St. Louis is home to the headquarters of ten of Missouri's eleven
Fortune 500 companies, six  Fortune 1,000 companies, and two of the top 30 Largest Private Companies in America, as ranked by Forbes. The area received the  All-America City Award in 2008.

history of St. Louis, Missouri began with the settlement of the St. Louis area by Native American mound builders who lived as part of the Mississippian culture from the 9th century to the 15th century, followed by other migrating tribal groups. Starting in the late 17th century, French explorers arrived. Spain took over in 1763 and a trading company established the settlement of St. Louis in February 1764. The city became part of the U.S. through the Louisiana Purchase in 1803. The American Civil War saw St. Louis had a small skirmish on its outskirts, but was held under Union control. After the war, the city expanded its railroad connections and industrial activity.
