New York began taking formal state censuses in 1825 both to determine representation in state government and to produce statistics the government might find useful. The state took a census every 10 years from 1825 through 1875, another in 1892, and then every 10 years again from 1905 to 1925. State censuses like the 1905 census are useful because they fall in between federal census years and provide an interim look at a population.
The 1905 census asked for the following details:
- street address, city/town, county, and election district
- name of each person whose usual place of abode on 1 June 1905 was in this family
- relationship to the head of household
- age at last birthday
- number of years in the United States
- citizenship status
- for residents of institutions, residence given upon admission
