Statewide Colorado Census records that exist are 1860 (Kansas,Nebraska, New Mexico and Utah territories), 1870, 1880, 1890 (fragment, see below), 1900, 1910, 1920, 1930 and 1940.

There are Industry and Agriculture Schedules 1860, 1870 and 1880. The Mortality Schedules for the years 1860, 1870 and 1880. The Union Veterans Schedules exist for 1890.

In 1860, multiple territorial censuses were taken. Many of them included parts of what is now Colorado.

For example, the census for Kansas Territory covered Arapahoe County, in central eastern Colorado. Nebraska Territory’s census, meanwhile, covered the following sections of Colorado: Boulder City, Boulder Creek Settlement, Gold Hill Settlement, Miraville City, Platte River Settlement .

Both the Kansas and Nebraska censuses from 1860 included parts of Denver City. Mora and Taos, New Mexico census records, meanwhile, included portions of southeast Colorado.

Leadville, which was a busy mining center at the time, was not enumerated at all and it was considered to be part of Utah Territory at the time.

Colorado Territory was formed in 1861. At that time, voters were registered. The Colorado State Archives has those original poll books on file, but only males are listed in them.

Pennsylvania Census Records

In 1866, another Colorado census was taken, however, most of those records no longer exist. Only the section that included northeastern Colorado still exists today.

Parts of Yuma and Washington County were listed in it, along with all of Sedgwick, Weld, Logan, Phillips, and Morgan. Those records are at the Colorado State Archives in a document that lists females under and over 18, along with males under and over 21.

A special federal census was taken in 1885. It included not only population information, but also information on manufacturing and agriculture. It also includes mortality returns.

Those records can be found in multiple places, including the National Archives/Rocky Mountain Region, the Colorado State Archives, the Denver Public Library, and the Colorado Historical Society.

There are abridged copies located in some counties. Those copies appear to be indexes because they list residents in alphabetical order. These abridged copies don’t include all of the data from the original or refer researchers to pages in the original, though. Therefore, anyone trying to do in-depth research should consult the original records.
