Prague has a local-government structure of two or three tiers, depending on the area of town. At the top is the Magistrate of the Capital City of Prague (Czech: Magistrát hlavního města Prahy), which is responsible for public transport; waste collection; municipal police; firefighting; ambulance services; cultural activities; care of historical sites; the Prague Zoo; and other activities of citywide significance.
Prague is divided into 10 municipal districts (1-10), 22 administrative districts (1-22), 57 municipal parts, or 112 cadastral areas.
Since 1990, the city has been divided into 56 (since 1992, 57) self-governing municipal parts (Czech: městské části). The parts are responsible for parks and environmental protection; ordering equipment for schools and volunteer firefighters; some cultural and sports activities; activities for seniors; some social and health programs; cemeteries; and collection of fees for dog tags and the like. Another important activity of the municipal parts is the ownership, maintenance and, sometimes, sale of public property, especially public housing.
Since 2001, the 57 municipal parts have been grouped into 22 numbered administrative districts (Czech: správní obvody), for national-government purposes. One administrative district has responsibility for providing certain services for the municipal parts. Those services include providing business licenses, identity cards and passports. The administrative district with such responsibility sometimes shares a name with the municipal part it serves. For example, the administrative district of Prague 19 provides those services to the municipal parts of Prague 19 (Kbely), Prague-Satalice and Prague-Vinoř. Residents of Satalice can get dog tags in their neighborhood but must go to Kbely, home of the Prague 19 government, to get an identity card.
Both the citywide government and the municipal districts have elected councils and mayors. The mayor of the Capital City of Prague is known as the primátor, which is sometimes translated into English as "lord mayor" (even though the Czech title carries no connotations of nobility).
Since 1960, Prague has been divided into 10 municipal districts. Those 10 districts are still used for addressing and transportation purposes and, for example, the organisation of courts and prosecutions. Street signs usually reflects the name of a municipal district and additionally add the name of the cadastral area (Czech: katastrální území). Thus, a sign in Kbely will say "Praha 9-Kbely," not "Praha 19." Prague residents are much more likely to use the name of a cadastral area, than the name of an administrative district in everyday communication.
