Cities in Pennsylvania are divided into four classes: Class 1, Class 2, Class 2A, and Class 3. Class 3 cities, which are the smallest, have either a mayor-council system or a council-manager system like that of a borough, although the mayor or city manager has more oversight and duties compared to their borough counterparts. Pittsburgh and Scranton are the state's only Class 2 and Class 2A cities respectively, and have mayors with some veto power, but are otherwise still governed mostly by their city councils.
