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.
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.
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.
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.
