State Census Records

The State Census of New York were taken every ten years from 1825 to 1875, in 1892, and again in 1905, 1915, and 1925; pre-1825 state censuses and state copies of those for 1855 to 1905 were destroyed in the 1911 state library fire. Most of the censuses that have survived can be found with the county clerk, although some are with the county historian or in other locations. For a list of the whereabouts of these censuses, consult Marilyn Douglas and Melinda Yates, comps., New York State Census Records, 1790–1925, Bibliography Bulletin 88 of the New York State Library (Albany, N.Y.: 1981), which has some errors and omissions. ¹⁾Roger D.
