Mill Plain, CT population, income and ZIP codes

Mill Plain CDP is a small town in Connecticut, with 1,980 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #121 of 215 ranked by population — larger than 43% of them. The median age here is 44.3 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 Mill Plain CDP earn a median of $190,250 a year, 142.2% above the national figure of $78,538 and 97% above the $96,484 median for the 159 Connecticut cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 3.8% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Mill Plain CDP is valued at $806,600, 165.9% above the national figure and 134% above the $344,200 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 94.7% 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. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

The Census withheld gross rent for Mill Plain CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
