Prefecture (administrative division)

Typical roles and characteristics

Prefectures commonly perform administrative tasks such as public order, civil registration, coordination of state services, and implementation of national policies at the local level. Depending on the country, a prefecture may be governed by an elected council and chief executive, or by a centrally appointed prefect acting as the national government’s representative.

Examples and national variations

• Japan: Japan’s primary subnational units are known as prefectures; the Japanese term ken (県) is used for many of them. Prefectures there have elected governors and assemblies.
• Greece: Historically used the term nomós (prefecture) for regional units of administration, though the precise structure has changed through modern reforms.
• France: The word préfecture refers both to the office and to the administrative centre of a department; the department itself is the larger territorial unit (department). The prefect is a state official who coordinates national services in the department (Prefectures in France).

Comparisons and terminology

In translation, a prefecture is often compared to an American state or a British county, but such comparisons are approximate: population, area, autonomy and legal powers differ widely. Some countries use the term to mean an administrative district, others emphasize the prefect’s office rather than the territory.

Origins and notable facts

The word comes from the Latin concept of a praefectura — an area under a praefectus. Today the term remains versatile: it can denote a level of government, the seat where administration is located, or the office-holder who represents national authority at the regional level.
