Records Available to You
Our microfilmed Federal records include the following types of materials:
Census Records
The Constitution requires that the Federal Government count the population of the United States every ten years. Census records provide basic facts about your ancestors and reveal clues to finding other records in the National Archives.
We have microfilm copies of the Federal population censuses for all states from 1790 to 1930, and also a comprehensive selection of indexes.
- Early censuses provide the name of the head of the household and the number of occupants.
- Later censuses reveal the names of each family member as well as age, marital status, occupation, state or country of birth, year of immigration, and year of naturalization.
- Census schedules are arranged by year and there under, by location.
- Most census schedules are searchable by head of household and some by any name provided on the census schedule.
Immigration Records (Ship's Passenger Lists)
With the creation of the Customs Bureau in 1820, the Federal Government began requiring passenger lists from ships docking at U.S. ports. Since then, over 55 million people have immigrated to the United States.
We have microfilm copies of ship's passenger lists from the following ports:
- Atlantic ports (small): Indexes 1820-1952, Passenger Lists 1820-1948
- Baltimore, MD: Index 1820-1952, Passenger Lists 1820-1909 (with gaps)

Ship's Passenger Lists documentation varies:

- Late 19th century and 20th century lists may include the traveler's place of birth, assets, health, last foreign residence, the name of a relative in the home town, information about previous journeys to the U.S., and their final U.S. destination.

Naturalization Records
To order naturalization records for these states, please e-mail: denver.archives@nara.gov.
Also view the New Mexico Index of Naturalizations.
Immigrants become U.S. citizens through naturalization. Upon meeting residency requirements, immigrants petition the courts for citizenship and take an oath of allegiance. Under former laws, immigrants could petition for citizenship in Federal, state, or county courts. Naturalization records may include the:
- Declaration of Intention
- Petition for Naturalization
- Certificate of Naturalization
We have naturalization records from Federal courts in Colorado, Montana, New Mexico, and Utah for the following time periods:
- Colorado: Denver, 1877-1972
- Montana: 1891-1929
- New Mexico: 1882-1917
- Utah: 1909-1930
The data in the naturalization records varies:
- Early naturalization records, from 1790 through 1906, typically provide an immigrant's name and country of origin.
- In 1906, the Bureau of Immigration and Naturalization standardized the naturalization process and began to require more detail on the naturalization forms.
