The Podlaskie Voivodeship in Poland, Polska is divided into 17 counties (powiats), including three municipal counties, and 14 rural counties. These are further divided into 118 communes (gminas). A Powiat (pronounced povyat) is the second level of Polish administrative division, between Voivodships and Communes. As such it is roughly equivalent to counties or districts in the United Kingdom. There is no official equivalent of the name in English.
Some of the towns in a Voivodship can be centres of more than one powiat. The reason is that in several cases the town itself and its surroundings form separate entities of administrative division. This is usually the case for large Polish cities, but can also apply to several smaller towns.
