The Department of Local Affairs' State Demography Office has completed its Vintage July 2009 Population Estimates for the state, counties and municipalities.
The new data has been posted on DOLA's website at: http://dola.colorado.gov/dlg/demog/index.html, select "Population" and "Population Totals" and then the geography you are interested in. Please note, there have been revisions to the data series 2001-2008 based on revised migration and housing unit data.
