Attica (region)
administrative region of Greece
Attica ( AT-ih-kə; Greek: Περιφέρεια Αττικής, romanized: Periféria Attikís, [periˈferi.a atiˈcis]) is an administrative region of Greece that encompasses the entire Athens metropolitan area, the core city of which is the country's capital and largest city, Athens. The region is coextensive with the former Attica Prefecture of Central Greece and covers a greater area than the historical region of Attica.
Overview
Located on the eastern edge of Central Greece, Attica covers about 3,808 square kilometres. In addition to Athens, it contains within its area the cities of Elefsina, 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 3,790,000 people live in the region, of whom more than 95% are inhabitants of the Athens metropolitan area. In 2019, Attica had the HDI of 0.912, the highest in Greece.
Administration
The region was established in the 1987 administrative reform, and until 2010 it comprised the 4 prefectures of Athens, East Attica, Piraeus and West Attica.
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.
Begin with the source’s own compact description: “Attica (region)” is administrative region of Greece. The dossier treats that line as a proposition to test through Attica, region and administrative, not as a finished interpretation.
Why this record matters
The phrase “administrative region of Greece” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 13, 2026. The linked authority identifier is Q758056. VIAF identifies the subject as 67145003863861340171. Authority coordinates are 38.000, 23.700. 1 of 5 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 2019, 1987, 2010 and 2011.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
