Rockville, CT population, income and ZIP codes

Rockville CDP is a mid-size town in Connecticut, with 6,657 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #54 of 215 ranked by population — larger than 75% of them. The median age here is 37.6 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 Rockville CDP earn a median of $51,607 a year, 34.3% below the national figure of $78,538 and 47% below the $96,484 median for the 159 Connecticut 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 23.9% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Rockville CDP is valued at $192,500, 36.6% below the national figure and 44% below the $344,200 peer median, while median gross rent runs $1,137 a month, 19.1% below the national figure, or roughly $13,644 across a full year. A household on the local median income would put about 26.4% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 27% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. 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.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
