Watertown CDP, CT in context

How this area compares with national benchmarks.

Watertown CDP is a small town in Connecticut, with 4,215 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #73 of 215 ranked by population — larger than 66% of them. The median age here is 42.5 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Watertown CDP earn a median of $98,003 a year, 24.8% above the national figure of $78,538 and within a couple of points of 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 13.8% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Watertown CDP is valued at $278,500, 8.2% below the national figure and 19% below the $344,200 peer median, while median gross rent runs $1,115 a month, 20.7% below the national figure, or roughly $13,380 across a full year. A household on the local median income would put about 13.7% 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 2.8×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

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.
