El Paso County is the most populous county in Colorado, with 655,044 residents, according to the U.S. Census Bureau, which reported this week where the heaviest population growth was in Colorado last year.
The fastest-growing county in Colorado between April 1, 2010, and July 1, 2013, was Denver County, whose population rose 6.5 percent over the period. Denver County was followed by Douglas at 7.2 percent, Weld at 6.7 percent, Broomfield at 6.5 percent and Adams at 6.2 percent.
Denver County added 49,415 people over the period, more than any other county in the state. It was followed by Arapahoe County, which grew by 34,995 people, El Paso County, which grew by 32,781 people, Douglas County at 20,498 residents and Jefferson County, with 17,234 new residents.
In the most populous county, behind El Paso County, is Denver County with 649,495 residents and Arapahoe County with 607,070 people.
This information is based on annual population estimates for each of the nation’s counties, county equivalents, metropolitan areas and micropolitan areas since the 2010 Census and up to July 1, 2013. Internet tables are available showing rankings and components of population change (births, deaths, migration).
Later this year, data will be available from County Business Patterns, which provide the economic side of the story. Annual statistics will be released on the number of establishments, employees and annual payroll for nearly 1,200 industries at the national, state and county levels.
Statistics on the number of people who commute from one specific county to another will also be released this spring.
