Colorado's population growth has shifted from the urban core to a band of towns along and just east of Interstate 25. This trend is driven by new home construction in the counties ringing metro Denver, priced well below what's left inside the city limits. The state's growth engine is now centered around Weld, Douglas, Larimer, and El Paso counties, with a notable influx of residents from Denver, Arapahoe, Boulder, and Jefferson counties. This shift has significant implications for the state's housing market and commuting patterns.
One of the most notable destinations for these migrating residents is Colorado Springs. The city added 2,288 residents between July 2024 and July 2025, a modest percentage increase, but significant in a year when many municipalities lost population. Real estate analysts attribute this to migration out of Denver, and regional economists highlight El Paso County's affordability compared to Denver. The presence of the Air Force Academy, Peterson and Schriever Space Force Bases, and Fort Carson provides stable employment, which is a rare commodity in growing exurbs. The city's vacancy rates have ticked up, but the addition of affordable housing complexes like the Sumner House is a positive development.
Erie, a town across the Boulder-Weld county line, has seen a 9.2% growth rate between July 2023 and July 2024, adding 3,261 residents. This growth is directly tied to spillover from Boulder County and the Denver area, as buyers priced out of Boulder look for more affordable options. Erie's transformation from a farm town to a thriving community with shopping centers, breweries, and restaurants is a testament to its appeal. The town's proximity to Boulder and the Denver area, coupled with newer subdivisions, makes it an attractive choice for families.
Windsor, straddling Larimer and Weld counties, has also experienced rapid growth. The town's population reached 41,734 in 2024, an increase of 1,342 residents or 3.3%. Weld County's demographic office highlights Windsor as one of southern Weld's fastest-growing areas. The town's ability to preserve its historic core while accommodating new subdivisions is a unique feature. Downtown Windsor's lake and shopping centers, coupled with the expansion of commercial corridors, make it an appealing destination for those priced out of Boulder County and the Denver metro.
Johnstown, spanning the Larimer-Weld county line, has seen significant growth, ranking 10th nationally among towns with over 20,000 residents. The town's growth is tied to the Granary development, a master-planned project with over 3,600 homes. This project, along the Interstate 25 corridor, is designed with parks, trails, and retail space, offering a balanced lifestyle. Johnstown's smaller size and less built-out nature appeal to buyers seeking new construction without the traffic found in nearby Erie.
Severance, a town northwest of Greeley, has experienced a remarkable 142.75% population increase over the decade, with a 6.6% growth rate in the most recent year. The town's growth is part of the same southern Weld build-out, drawing households from Boulder County and the Denver metro. Severance's small size allows for new subdivisions to outnumber the original core, and the town retains a few pre-boom era fixtures, such as Bruce's Bar, surrounded by new developments.
Douglas County, with its county seat in Castle Rock, has added 6,345 residents between July 2024 and July 2025, a 1.6% increase. The county's median household income is the highest in Colorado, and its net in-migration follows the core-to-suburb pattern. Castle Rock, Castle Pines, and Parker continue to draw permits for single-family and townhome construction. The county's location between Denver and Colorado Springs provides new residents with commuting options to both job markets.
The patterns of migration in Colorado are clear: residents are moving away from the urban core of Denver, Arapahoe, Boulder, and Jefferson counties towards the suburbs of Weld, Douglas, Larimer, and El Paso counties. This shift has far-reaching consequences, including longer commutes, faster school enrollment growth, and a housing market where affordable options are moving farther from downtown. The state's demographers expect this trend to continue as construction remains concentrated in these counties, reshaping the Front Range's demographics and lifestyle.
