New York State Census Records Availability - Due to the high volume of immigration, the state of New York took a census enumeration every 10 years between 1825 and 1875, then again in 1892, 1905, 1915 and 1925. NY state censuses taken before 1915 are kept at the county level. Contact the County Clerk in the county of interest to ask where the originals are held for that county. The 1865 & 1875 NY state census records included schedules which recorded marriages and deaths occurring in the census year. These may prove helpful if you are lucky enough to have ancestors who had these events occur during the census year. Most of the New York state census records are not indexed. Some of these early NY state censuses are available online at New York State Census Collection at Ancestry. For more helpful information about these early NY censuses See More New York State Census Records Info.
