Centennial, CO population, income and ZIP codes

Centennial city is a mid-size city in Colorado, with 107,386 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #11 of 482 ranked by population — larger than 97% of them. The median age here is 41.8 years against 39.1 nationally, a slightly older profile than the country as a whole. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Centennial city earn a median of $128,167 a year, 63.2% above the national figure of $78,538 and 48% 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 3.1% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Centennial city is valued at $626,700, 106.6% above the national figure and 38% above the $453,600 peer median, while median gross rent runs $2,061 a month, 46.6% above the national figure, or roughly $24,732 across a full year. A household on the local median income would put about 19.3% 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 4.9×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 81.3% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
