Colorado Census Research

Federal census records for Colorado began in 1870, and were taken every ten years.

 

Territorial and State censuses: The area which would later become Colorado was included in parts of several territorial censuses in 1860.

  • Arapahoe County was included in the Kansas territorial census in 1860.
  • Boulder City, Boulder Creek Settlement, Gold Hill Settlement, Miraville City, and the Platte River Settlement were enumerated with Nebraska Territory.
  • Denver City was partly enumerated with Nebraska and partly with the Kansas territorial census.
  • The southeast portion of Colorado (known as the Rio Grande Valley) was enumerated in parts of Taos and Mora counties of New Mexico Territory.
  • Leadville, although a booming mining town at the time and located in what is now Lake County, was in Utah Territory and not enumerated.

A Colorado state census was taken in 1866, but the only available returns are for the northeastern section which included the counties of Logan, Morgan, Phillips, Sedgwick, Weld, and parts of Washington and Yuma. The records are available at the Colorado State Archives.

In 1885, a more complete census of Colorado included population, mortality, agricultural, and manufacturing schedules. The population schedules are available on Ancestry.com as the Colorado State Census, 1885. Other schedules can be found at the Colorado State Archives. Both state and county copies of this census exist, though for complete information, the researcher will need to use the original state copy.

 

Colorado Vital Records

Statewide registration of births and deaths began in 1875, though compliance was intermittent. Statewide registration was successfully implemented in 1910 for births and 1900 for deaths. Most marriage records are still maintained by individual county clerks.

Colorado vital records are restricted by law to those with a proven direct relationship or tangible interest. Colorado Department of Public Health and Environment's Genealogy page provides useful information on sources and ordering of vital records.

  • Colorado Vital Records: Holds records of births since 1910; deaths from 1900; marriages from 1900-1939 and 1975-present; and divorces 1851-1939 and 1968-present. For marriages from 1940 to 1974 or divorces from 1940-1967, contact the county where the license or decree of divorce was issued.
  • Colorado State Archives: Holds a microfiche index of approximately 3,000 Colorado births from 1863-1899, and an index of marriages and divorces from 1900-1939.
  • Western States marriage index (BYU Idaho) special collections: a searchable index to marriages in several western states, including Colorado. See the web site for specific counties and years included in the index.
