Boulder growth takes the slow road

Boulder County grew from 291,288 residents in 2000 to 294,567 in 2010 – a growth of only 1.1 percent but enough to keep it among the top 10 biggest counties in Colorado, according to the U.S. Census Bureau’s initial results from the 2010 Census.

However, Boulder dropped from being the sixth biggest county in 2000 to the seventh in that 10-year period, trading places with Larimer County, which grew from 251,494 resident in 2000 to a population of 299,630 last year – an increase of 19.1 percent.

El Paso jumped from the third biggest county in 2000 to the No. 1 slot in 2010 with a growth of 20.4 percent that took it from 516,929 to 622,263 residents, surpassing Denver, which grew only 8.2 percent to a population of 600,158.

However, El Paso was not the fastest-growing county in Colorado from 2000 to 2010: Douglas County was with a growth of 62.4 percent, followed by Weld County, 39.7 percent, and Garfield County, 28.8 percent. Several other counties also had higher growth rates than El Paso’s.

The city of Boulder gained 2,712 residents in the 10-year period, registering a population of 97,385 in 2010, for a growth of 2.9 percent. It fell in rank from the ninth biggest incorporated community in Colorado to No. 11.

The city (and county) of Denver retained the top slot for the biggest city in the state, and Colorado Springs and Aurora stayed in the No. 2 and 3 slots, growing 15.4 percent and 17.6 percent, respectively. The city of Fort Collins, with growth of 21.4 percent, went from 118,652 in 2000 to 143,986 residents last year, and went from the fifth biggest city 10 years ago to the fourth biggest in 2010.

Castle Rock grew the fastest – 138.5 percent – over the 10-year period, followed by Commerce City, 118.7 percent, and Parker, 92.3 percent.
