The Ionian Islands Region (Περιφέρεια Ιονίων Νήσων) is one of the thirteen administrative regions of Greece. The administrative region does not include all of the Ionian Islands; the island of Kythera, which historically was part of the island group, was separated and integrated to the (far away) Attica Region.
The population of the Ionian Islands in 2011 was 207,855, decreased by 1.5% compared to the population in 2001. Nevertheless, the region remains the third by population density with 90.1/km² nationwide, well above the national of 81.96/km². The most populous of the major islands is Corfu with a population of 104,371, followed by Zante (40,759), Cephalonia (35,801), Leucas (23,693) and Ithaca (3,231). In 2001, the foreign-born population was 19,360 or 9.3%, the majority of which was concentrated in Corfu and Zante. Most of them originate from Albania (13,536). The fertility rate for 2011 according to Eurostat was 1.35 live births per woman.
