Census Records - State Library of Pennsylvania
All of the National Archives microfilm publications relating to Pennsylvania, including the federal population census 1790-1940 (except for 1890 which was destroyed by fire in 1921) are in the collection. Except for 1870 there is a name index for each of the Pennsylvania population census schedules. Book indexes list the heads of families from 1790 through 1860. For 1870, only portions of the Pennsylvania census have been indexed. The 1880 Soundex Index includes only households with children aged ten years and younger but the 1900 Soundex Index and the 1910 Miracode Index include all heads of families.
