Grand Isle, ME population, income and ZIP codes

Grand Isle CDP is a very small community in Maine, with 244 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #152 of 155 ranked by population — larger than 1% of them. The median age here is 61 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 Grand Isle CDP earn a median of $36,000 a year, 54.2% below the national figure of $78,538 and 39% below the $58,992 median for the 106 Maine cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 15.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Grand Isle CDP is valued at $75,000, 75.3% below the national figure and 66% below the $221,600 peer median, while median gross rent runs $510 a month, 63.7% below the national figure, or roughly $6,120 across a full year. A household on the local median income would put about 17% 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 2.1×, 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. 75.4% 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.

A median age of 61 puts Grand Isle 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 244 residents, a handful of survey responses moves every median on this page. Compare Grand Isle CDP against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
