Denver Metro Communities Ranked by 5-Year Population Growth

By Jessica Car · Updated July 2026

Where the Denver metro is actually growing (and where it isn't) matters for relocation in two practical ways. Fast-growing communities tend to have more new construction (more inventory choice, less established character), and they tend to have services and infrastructure under more strain (school enrollment, traffic, water, build-out of retail).

This list ranks every community by its published 5-year population growth. Timnath, Severance, Erie, and Castle Pines have grown 40–80% over recent five-year windows; these are the new-construction frontiers along the I-25 corridor. The Boulder Area, Central Denver, and most established West Metro communities sit at the slow-growth or stable end, built out, mostly stable population, minimal new construction.

Two things to read alongside this number: (1) absolute population matters too; 60% growth on a 2,000-resident town is a different reality than 30% growth on a 100,000-resident city, and (2) the projected-population numbers in each community's Development section show whether the growth trend is expected to continue. Together, these surface where supply is most likely to lag demand over the next 5 years.

Each axis ranks the same 63 communities on a different dimension. A community that wins on one rarely wins on all; these views are complementary, not competing. See all rankings →
