Johnstown town, CO in context

How this area compares with national benchmarks.

Johnstown town is a mid-size town in Colorado, with 18,075 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #45 of 482 ranked by population — larger than 90% of them. The median age here is 34 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Johnstown town earn a median of $130,851 a year, 66.6% above the national figure of $78,538 and 51% above the $86,484 median for the 223 Colorado cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 2.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Johnstown town is valued at $493,500, 62.7% above the national figure and 9% above the $453,600 peer median, while median gross rent runs $1,767 a month, 25.7% above the national figure, or roughly $21,204 across a full year. A household on the local median income would put about 16.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 77.3% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

All values below were released by the Census for this exact geography, with no gap-filling on our side. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
