Finding Aid for the 1890 New York City, New York Police Census

There's a finding aid of great value for those who had ancestors in New York County in 1890 (what is now Manhattan and the western Bronx and the Islands in the East River.)

Most of the 1890 regular federal census, except for the enumeration of Civil War Vets, does not exist. In 1890 New York City was under counted in the federal census. Local leaders had the police force do a recount.The 1890 Police census began on 29 September and was mostly completed by 14 October.

Of the 1008 books of this recount, 894 are extant and are on 59 rolls of microfilm at the FamilySearch Library, NYC Archives, Ancestry.com$, and various NYC libraries. This police census gives name, age, and gender. It does not indicate relationship, but in the instances I have checked families are listed together.
