Learn about the 2020 Boulder Census here.

Boulder experienced the lowest rate of growth since pre-WWII

In the last decade, Boulder's population grew by 2.9 percent, from 94,673 residents to 97,385. This is the second lowest rate of growth since the 1890s. The only decade with a lower rate was the 1920s.

The number of school-age children in Boulder decreased slightly

The number of school-age children (ages 5-17) in Boulder has a cyclical pattern, and has averaged around 9,600 people since 1980. The data indicates this pattern will continue, as people aged 0 to 8 increased in Boulder from 2000 to 2010, and all will be school aged in 2020.

Boulder’s racial diversity has not changed

Boulder remains similar in racial diversity as in 2000, while the nation became more diverse. Eighty-eight percent of Boulder’s population is White, with a 0.3 percent decrease from 2000, while the nation saw a percentage decrease of nearly 3 percent. Both the U.S. and Boulder’s population has more Asians, Pacific Islanders, and persons of two or more races. Boulder has a lower percentage of African American residents and a higher percentage of American Indians when compared to the nation. The number of persons of Hispanic origin rose by 8.3 percent in Boulder, while the national increase was 43 percent.

Non-family and single households continue to rise

Consistent with national and regional trends, the number of family households in Boulder has decreased since 2000, while the numbers of non-family and single person households have increased.

Boulder’s average household size continued to drop

Consistent with nationwide and regional trends, the number of persons per household in Boulder has decreased almost continuously since 1970. Since 2000, the number of persons per household in Boulder decreased at a slightly higher rate (from 2.2 to 2.16) than the national average (from 2.59 to 2.58). Since 1970, Boulder has housed, on average, fewer people per household than the region or the nation.

Baby Boomers are staying

Boulder’s 55-59 year old population grew by 53 percent and 60-64 year old population grew by 80 percent, reflecting the aging of the baby boom generation. As the map below shows, this age group increased in north and central Boulder. These age groups make up almost 10 percent of Boulder’s population. The 15-24 age range increased, reflecting the increase in University enrollments over the last 10 years.

More people are living in group quarters

There are more people living in non-institutionalized group quarters (e.g., student housing) in Boulder. The number of institutionalized persons 65 years and older has declined from 586 in 2000 to 419 in 2010, indicating that less of the senior population is living in skilled nursing homes.

North Boulder added the most housing units in the last decade

The census tracts in North Boulder added the most housing units, followed by the census tract that includes the Bear Creek apartments at Williams Village. Central and east Boulder also added units.

Boulder’s vacancy rate doubled

The number of vacant housing units doubled since 2000. The 2010 vacancy rate is 5.01 percent, rising from 2.8 percent in 2000; however, Boulder’s vacancy rate is still significantly lower than the average for Colorado (10.8 percent) and the United States (11.4 percent). Of the vacant units, the majority were for rent or for sale. Housing units vacant due to seasonal, occasional, or recreational use decreased from 2000.
