# State censuses in the United States

Throughout U.S. history, various U.S. states conducted their own censuses. These censuses were often conducted every ten years, in years ending with a five to complement the U.S. federal census (which is carried out in years that end with zero). Also, some of these censuses were conducted in U.S. states while they were still U.S. territories (before they became U.S. states).
No state has conducted a state census since the last Massachusetts state census was conducted in 1985.

| New Mexico | 1790, 1823, 1845, and 1885⊗. Its first three censuses were conducted when New Mexico was still under Spanish rule. |
| New York | 1698, 1703, 1712, 1723, 1731, 1737, 1746, 1749, 1756, 1771, 1786⊗, 1790, 1825, 1835, 1845, 1855, 1865, 1875, 1892, 1905, 1915, and 1925. Only the name of the head of household is listed in New York state censuses from 1825 to 1845. Beginning in 1855, the name of every person in the household is listed. The 1855 to 1875 New York state censuses asked the person for the name of the county that one was born in if one was born in New York State. Also, the 1865 New York state census asked many questions about military service. New York did not conduct a census in 1885 because its Governor David B. Hill refused to support the proposed census due to its extravagance and cost. Governor Hill objected to the idea of spending so much state money on a state census that was as extravagant as the 1880 U.S. Census. The 1892 New York state census is more vague, asking only for a country of birth (rather than a specific U.S. state or New York county of birth), not indicating relationships of various people to each other, and not indicating where new families begin on the census forms. Indeed, the 1892 New York state census contained only seven questions — name, sex, age, color (race), country of birth, citizenship status, and occupation. Meanwhile, the censuses from 1905 to 1925 asked for relationships of people to each other but also only asked for a country of birth. Also, the 1925 New York state census asked for the date and place of naturalization for naturalized U.S. citizens. |
