Denver’s Capitol Hill is home to the sixth largest share of millennials in the country, with 66 percent of the neighborhood’s population belonging to city dwellers between the ages of 22 and 37, according to a new study by apartment search website RentCafé.

“This is the largest generational group right now in the metro Denver region and, indeed, in many parts of the country,” said Patty Silverstein, president and chief economist with Colorado-based Development Research Partners. “Just by sheer numbers, they have a large impact. It’s definitely a very important force.”

The study estimates that the Cap Hill ZIP code 80203 is packed with 13,500 millennial residents. ZIP codes in Chicago, Philadelphia, Manhattan, Boston and Washington, D.C., beat out the downtown Denver neighborhood with larger shares of young adult residents.

Denver also boasts four ZIP codes grouped in the Top 20 of areas with the highest increases in millenials in the country: 80206, 80209, 80224 and 80237.

Statewide, eight out of Colorado’s Top 10 trending millennial ZIP codes can also be found in Denver, but the No. 2 and No. 10 spots are located further south in Colorado Springs. ZIP codes 80925 and 80907 in Colorado Springs had a 35.7-percent and 26.9-percent jump, respectively, in millennials in the past five years, according to the study.

The Congress Park and Hampden South areas of Denver made the study’s Top 20 list of national ZIP codes with the highest millennial spike in a 5-year-period. Congress Park’s young adult population grew by 37 percent, with Hampden South increasing by 33 percent in five years.

The study said to consider these hot spots to be up-and-coming neighborhoods millennials have set their sights on.
