Pennsylvania State and Territorial Census
There were no state censuses taken in Pennsylvania. However, from 1779 through 1863 taxpayer enumerations were taken at 7-year intervals. Those records are known as the Ceptennial Census records. Only some of them are still in existence today. The Salt Lake City Family History Library (GHL) and the Pennsylvania State Archives have microfilmed copies of those records that still exist on file.
