I read some answers that were "number of residents" but I don't think this is the full answer. Because in a single town, there is the borough and the township. For example, take the town Ephrata, PA. There is the town of Ephrata, Ephrata Township and Ephrata Borough. The borough and township are both within the town of Ephrata.
