Cousins Island, ME population, income and ZIP codes

Cousins Island CDP is a very small community in Maine, with 509 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #136 of 155 ranked by population — larger than 12% of them. The median age here is 59.9 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 Cousins Island CDP earn a median of $121,250 a year, 54.4% above the national figure of $78,538 and 106% above the $58,992 median for the 106 Maine 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 0% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Cousins Island CDP is valued at $634,100, 109% above the national figure and 186% above the $221,600 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 5.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 94.9% 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. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 59.9 puts Cousins Island 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 509 residents, a handful of survey responses moves every median on this page. Compare Cousins Island CDP against its county rather than against national figures.

The Census withheld gross rent for Cousins Island 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.
