Guilford, ME population, income and ZIP codes

Guilford CDP is a very small community in Maine, with 630 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #124 of 155 ranked by population — larger than 20% of them. The median age here is 52.5 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 Guilford CDP earn a median of $41,250 a year, 47.5% below the national figure of $78,538 and 30% below the $58,992 median for the 106 Maine cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 16.5% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Guilford CDP is valued at $118,500, 60.9% below the national figure and 47% below the $221,600 peer median, while median gross rent runs $488 a month, 65.3% below the national figure, or roughly $5,856 across a full year. A household on the local median income would put about 14.2% 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 2.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 65% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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 52.5 puts Guilford 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 630 residents, a handful of survey responses moves every median on this page. Compare Guilford CDP against its county rather than against national figures.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. 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.
