Greece received a new administrative division on 1 January 2011 as part of an overall administrative reform, which was named after Kallikratis, a Greek architect from the mid-5th century BC.

Since 2011, Greece has been divided into 13 administrative regions, known as 'peripheries'. These administrative regions are in turn subdivided into 74 regional units, the 'perifereiaki enotita' or prefectures.

The regional units, which no longer have their own administration, are in turn subdivided into 325 municipalities or 'demoi'. In addition, since 1926, Greece has had one autonomous region under its own Greek Orthodox administration, namely Agion Oros or the monastic state of Athos in Chalkidiki (Northern Greece).

The 13 administrative regions of Greece are Attica (1), Central Greece (2), Central Macedonia (3), Crete (4), Eastern Macedonia and Thrace (5), Epirus (6), Ionian Islands (7), Northern Aegean (8), Peloponnese (9), Southern Aegean (10), Thessaly (11), Western Greece (12) and Western Macedonia (13).

With the administrative reorganisation of 2011, Chios became a regional unit of the North Aegean Islands administrative region, which further consists of the regional units Ikaria, Lesvos, Limnos and Samos.
