Attica Region (Greek: ? ?, romanized: Periféria Attikís, [peri'feri.a ati'cis]) is an administrative region of Greece, that encompasses the entire metropolitan area of Athens, the country's capital and largest city. The region is coextensive with the former Attica Prefecture of Central Greece, but covers a greater area than the historical region of Attica.
Located on the eastern edge of Central Greece, Attica covers about 3,808 square kilometers. In addition to Athens, it contains within its area the cities of Eleusis, Megara, Laurium, and Marathon, as well as a small part of the Peloponnese peninsula and the islands of Salamis, Aegina, Angistri, Poros, Hydra, Spetses, Kythira, and Antikythera. About 3,750,000 people live in the region, of whom more than 95% are inhabitants of the Athens metropolitan area.
With the 2010 Kallikratis plan, the region's powers and authority were completely redefined and extended. Since 1 January 2011, the region represents the second-level local administration. While being supervised by the Decentralized Administration of Attica, it is now an independent self-governing body with powers and a budget comparable to the former prefectures.
The Gross domestic product (GDP) of the region was 87.4 billion EUR in 2018, accounting for about 47% of the Greek economic output. GDP per capita adjusted for purchasing power was 28,000 EUR or 93% of the EU27 average in the same year. The GDP per employee was 99% of the EU average. Attica is the region in Greece with the highest GDP per capita. Despite that, the unemployment rate stood at 21.6% in 2017.
The main roads and highways of Attica are:
Numerous ferry lines, both normal ferries and the "flying dolphins" (fast sea vessels), connect the port of Piraeus with the islands of the region.
