Townships are not "subdivisions" of counties; rather, they are separate and distinct in definition and operation from counties. Townships, regardless of population (example, Cold Spring Township in far northern Lebanon County has long had zero or next-to zero residents) are their political entities. Most townships have a 3-member board of supervisors who are paid a small annual stipend. There are at least 2 categories of townships, but what separates them is not strictly population based. The Municipal Planning Code has all that.
