Stamford, CT population, income and ZIP codes

Stamford city is a mid-size city in Connecticut, with 135,806 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #2 of 215 ranked by population — larger than 99% of them. The median age here is 38.2 years against 39.1 nationally, a slightly younger 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 Stamford city earn a median of $107,474 a year, 36.8% above the national figure of $78,538 and 11% above 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 9.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Stamford city is valued at $614,300, 102.5% above the national figure and 78% above the $344,200 peer median, while median gross rent runs $2,207 a month, 57% above the national figure, or roughly $26,484 across a full year. A household on the local median income would put about 24.6% 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 5.7×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 47.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
