In the years following a decennial census, the US Census Bureau releases in March its county population estimates for July 1 of the preceding year. This is known as their annual postcensal estimates. A few days ago, the bureau’s July 1, 2013 population estimates were released. In this post, we will take a look at Denver’s and other Colorado counties’ population estimates. You can read last year’s post on this topic by clicking here.

For the fifth time in the past six years, Denver County has led the state in numeric population growth according to the US Census Bureau. The Census Bureau’s recently released 2013 population estimates show that Denver County (the City and County of Denver) had a population of 649,495 on July 1, 2013, an increase of 14,953 over their July 2012 estimate of 634,542. Denver’s 2010 Census population count was 600,158.

Here are two tables I’ve prepared showing the “Vintage 2013” postcensal estimates for the Top 10 Colorado counties in both numeric and percentage population gain between the 2012 and 2013 (click to embiggen):



Next, let’s take a look at the Top 10 Colorado counties in both numeric and percentage population gain between the 2010 Census and the new July 2013 estimates:
