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 .
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.
