Draft Population Estimates


The Colorado Department of Local Affairs has created population estimates for use in many areas including the Conservation Trust Fund program as the basis of distributing lottery funds.

These estimates are based on the April 1st, 2010 Census plus annual data on births, deaths, net migration, change in group quarters facilities, and housing unit change. The estimates for the previous year will be different than the one released this year because of the updated census migration estimate data.
