Arizona Census

Starting in 1790, federal population schedules were taken every 10 years in the United States. Click here for more information about federal census records. Arizona was a part of Mexico until the end of the Mexican-American War in 1848, when it was given to the United States as part of the Treaty of Guadalupe Hidalgo. Therefore, Arizona was not included in census prior to 1850. Additionally, until 1862, Arizona was part of the New Mexico territory.

Non-Population Schedules for Arizona
Federal non-population schedules included such things mortality schedules, agriculture schedules, slave schedules, and manufacturing schedules.

Online State and Territorial Censuses
State censuses are census records that were taken at the state-level rather than at the federal. Often, but not always, a state took their census in ten year increments 5 years from when the Federal Census was taken, such as 1885. State censuses can even serve as substitutes for missing federal censuses. For more information on state censuses, visit United States Census Bureau. Territorial censuses were taken by the federal government to count the population in federal territories. The government needed to count the population in the territory to see if it could qualify for statehood. For more information on territorial censuses, visit the US Territorial Census page.
