Crete is one of the most powerful economic parts of Greece based on production of agricultural products, research, green power production and, of course, touristic services.
The economy of Crete, which was mainly based on farming, and fishing, began to change visibly during the 1970s. While an emphasis remains on farming and stock breeding, due to the climate and terrain of the island, there has been a drop in manufacturing and an observable expansion in its service industries (mainly tourism-related). All three sectors of the Cretan economy (agriculture, processing-packaging, services), are directly connected and interdependent. The island has a per capita income close to 100% of the Greek average, while unemployment is almost half of that of the country overall.
As in other regions of Greece, olive growing is also a significant industry; a small amount of citrons are still cultivated on the island.
The island has three significant airports, Nikos Kazantzakis at Heraklion, the Daskalogiannis airport at Chania and a smaller one in Sitia. The first two serve international routes, as the main gateways to the island for travellers.
