Draft 2012 CTF Estimates
The Colorado Department of Local Affairs, State Demography Office (SDO) has prepared draft July 1, 2012 population estimates for your review. These population estimates, once finalized, will be the basis for the distribution of Conservation Trust Fund (CTF) lottery funds to your jurisdiction.
The July 1, 2012 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 - July 1, 2011 will be different than the one released last year because of the updated census migration estimate data.
Counties and municipalities should review Table 2 in particular. Special districts, municipalities with special districts, and counties should review Table 4. Please also provide any updates to contact information.
Local Governments are provided thirty (30) days in which they can review and challenge the population estimate for their entity. In order to file a challenge, you must send a letter to Tamra Hooper, Conservation Trust Fund Administrator, 1313 Sherman St., Room 521, Denver CO 80203 or firstname.lastname@example.org no later than July 17, 2013. The letter should indicate your concern about the estimate, describe the basis of your concern with supporting data, if possible, and the name of a contact person that staff can work with to resolve any differences.
Local government input and involvement in our estimates process ensures the most accurate data for Conservation Trust Fund distribution. Thank you for your assistance and cooperation.
TABLE 1: Table 1 provides April 2010 Census, Adjusted April 1, 2010 Census, July 1, 2011 estimates and July 1, 2012 estimates of county population. It also includes components of change from July 1, 2010-2012 along with symptomatic data.

Each county selection includes a sheet for the county as a whole, one for each incorporated place, and one for the unincorporated part of the county.

TABLE 4: Table 4 provides the July 1, 2012 estimates of population and households by CTF-receiving special district. The estimates are listed first for the entire county, and then for each special district. The special district total is listed first, and then its municipal and unincorporated components. Definitions for each column are given at the bottom of each page.
METHODOLOGY: The methodology provides a description of the methods used for creation of the annual population estimates for counties, municipalities and CTF-receiving special districts.
