An Act amending Title 11 (Cities) of the Pennsylvania Consolidated Statutes, providing for city classification; making a repeal; and making editorial changes.

This bill updates Pennsylvania's city classification system by establishing four new classes based on population size, ranging from first class cities with over one million residents to third class cities with fewer than 250,000. It replaces the old 1895 law and requires that a city's classification only change after two consecutive federal censuses show a sustained population shift, preventing changes due to temporary fluctuations. For cities with home rule or optional charters, any change in classification requires a vote by the city's electors to amend their charter. The new rules take effect on January 1 following the next municipal election that occurs at least 180 days after the Governor certifies the change.
