From the first federal census of 1790, the records are nearly complete for Pennsylvania, and microfilms of the federal copies are widely available at the National Archives—Mid-Atlantic Region , the Pennsylvania State Archives, the Historical Society of Pennsylvania, the Pennsylvania State Library, the Carnegie Library of Pittsburgh (see Pennsylvania Archives, Libraries, and Societies), and other libraries. Two enumerations were taken in Philadelphia in 1870; the second includes the street address. Gaps in the records are the following: 1800 (parts of Bedford and Westmoreland counties); 1810 (parts of Bedford, Cumberland, and Philadelphia counties); and 1820 (parts of Lancaster, Lehigh, Luzerne, and Monroe counties). There are three published book indexes for the 1800 census and two for 1810. The 1850 census also has two indexes, one arranged by county. An all-name index to the 1850 to 1880 censuses for Pittsburgh and Allegheny City is at the Carnegie Library of Pittsburgh. For the 1910 Miracode, Philadelphia County is indexed apart from the rest of the commonwealth. The original schedules of the 1880 census, microfilmed by the National Archives, are now in the state archives. The state copies of the 1840 to 1870 censuses are no longer extant, but a few county copies are known to exist. Microfilm of the non-population and mortality schedules for 1850 to 1880 are at the state library and at the National Archives—Mid-Atlantic Region. Pennsylvania took no state censuses, but an enumeration of taxpayers compiled every seven years from 1779 through 1863 is commonly called the Septennial Census. These records have only survived in small numbers and are available at the state archives and on microfilm at the The Family History Library (FHL) at Salt Lake City.
