The geopolitical arrangements of the commune are slightly different from those typical of Corsica and France. Usually an arrondissement includes cantons and a canton includes one to several communes including the chef-lieu, "chief place", from which the canton takes its name. The city of Ajaccio is one commune, but it contains four cantons, Cantons 1–4, and a fraction of Canton 5. The latter contains three other communes: Bastelicaccia, Alata and Villanova, making a total of four communes for the five cantons of Ajaccio.
