펜실베이니아주는 몇 개의 도시가 있는가?
This is a list of cities in Pennsylvania, of which there are 57. Cities may theoretically be first-class, second-class, second-class A, or third-class (of which there are 54), according to population and adoption of certain ordinances. However, all first-class (of which there is 1), second-class (of which there is 1), and second-class A (of which there is 1) cities, as well as 24 third-class cities, have adopted Home Rule Charters, which change a city's relationship with the state so much that they are generally no longer considered to be a city under state law. However, they are still considered cities for classification purposes. Unlike other similar lists for Pennsylvania's towns and boroughs and townships, this list "does" include cities with Home Rule Charters, as, unlike in the previous cases, excluding them would severely limit the comprehensibility of this list. As in those previous cases, however, it should be strongly emphasized that these are not really cities under state law, and they are therefore also listed in "List of Pennsylvania Municipalities and Counties with Home Rule Charters, Optional Charters, or Optional Plans," and are indicated below.
