Federal censuses are private for 72 years; the 1930 census is scheduled for release in 2002. There never was a restriction on State Censuses that I've heard of. I believe that the census was taken in all counties extant in the census year, but all the State copies were lost in the 1911 Capitol fire and some of the County copies were just plain lost. One town that I know of has its copy of an early census that does not exist for the whole county. There may be others. All the original 1915 and 1925 copies exist and are in the custody of the NYS Archives. Marie
