Crystal Lake, CT population, income and ZIP codes

Crystal Lake CDP is a small town in Connecticut, with 1,963 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #123 of 215 ranked by population — larger than 42% of them. The median age here is 51.1 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 Crystal Lake CDP earn a median of $142,642 a year, 81.6% above the national figure of $78,538 and 48% above 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 1.5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Crystal Lake CDP is valued at $345,300, 13.8% above the national figure and within a couple of points of the $344,200 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.4×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 91.3% 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. 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.

A median age of 51.1 puts Crystal Lake 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.

The Census withheld gross rent for Crystal Lake 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.
