Derby city, CT in context

How this area compares with national benchmarks.

Derby city is a mid-size town in Connecticut, with 12,359 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #33 of 215 ranked by population — larger than 85% of them. The median age here is 46.3 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Derby city earn a median of $76,263 a year, 2.9% below the national figure of $78,538 and 21% below the $96,484 median for the 159 Connecticut cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 9.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Derby city is valued at $242,300, 20.1% below the national figure and 30% below the $344,200 peer median, while median gross rent runs $1,453 a month, 3.3% above the national figure, or roughly $17,436 across a full year. A household on the local median income would put about 22.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.
