Administrative divisions

Jersey is divided into twelve parishes (which have civil and religious functions), the largest being St Ouen and the smallest St Clement. They are all named after their parish church. The ''connétable'' is the head of the parish. They are elected at island general elections and sit ''ex oficio'' in the States Assembly. The parishes have various civil administrative functions, such as roads (managed by the Road Committee) and policing (through the

The highest point on the island is Les Platons at . There are several smaller island groups that are part of the Bailiwick of Jersey, such as Les Minquiers and Les Écrehous, however unlike the smaller islands of the Bailiwick of Guernsey, none of these are permanently inhabited.


Settlements

The largest settlement is the town of St Helier, including the built-up area of southern St Helier and neighbouring areas such as Georgetown, which also plays host to the island's seat of government. The town is the central business district, hosting a large proportion of the island's retail and employment, such as the finance industry. Outside of the town, many islanders live in suburban and rural settlements, especially along main roads leading out of town, and even the more rural areas of the island have considerable amounts of development (St Ouen, the least densely populated parish, still has 270 persons per square kilometre).
