Cornwall, CT population, income and ZIP codes

Cornwall CDP is a very small community in Connecticut, with 65 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #211 of 215 ranked by population — larger than 1% of them. The median age here is 61.5 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Cornwall CDP earn a median of $134,167 a year, 70.8% above the national figure of $78,538 and 39% 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 12.3% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Cornwall CDP is valued at not published, while median gross rent runs not published a month. 100% 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.

A median age of 61.5 puts Cornwall CDP well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 65 residents, a handful of survey responses moves every median on this page. Compare Cornwall CDP against its county rather than against national figures.

The Census withheld home value, gross rent for Cornwall 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.
