Draft 2013 CTF Population Estimates

Letter to Local Governments (PDF)

The Colorado Department of Local Affairs, State Demography Office (SDO) has prepared draft July 1, 2013 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, 2013 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, 2012 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(Municipalities in Multiple Counties should look at the “Multi-County” file to see their total estimates). 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 Norton, Conservation Trust Fund Administrator, 1313 Sherman St., Room 521, Denver, CO 80203 or tamra.norton@state.co.us, no later than December 17, 2014. 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.

Please send questions to Rob Kemp at 303-864-7755, robert.kemp@state.co.us.  

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 through July 1, 2013 estimates of county population. It also includes components of change from July 1, 2012-2013 along with symptomatic data.

 


TABLE 2: Table 2 provides April 2010 Census, Adjusted April 1, 2010 Census, through  July 1, 2013 estimates of population and housing units, with related input data. This sheet is particularly useful for evaluating the estimates. 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 3: In Table 3, the municipal estimates are broken down into household and group quarters populations, and calculation of the implied vacancy rate is shown. Definitions for each column are given at the bottom of each page.


TABLE 4: Table 4 provides the July 1, 2013 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.
