West Kennebunk, ME population, income and ZIP codes

West Kennebunk CDP is a small town in Maine, with 1,367 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #90 of 155 ranked by population — larger than 42% of them. The median age here is 33.5 years against 39.1 nationally, a slightly younger profile than the country as a whole. 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 West Kennebunk CDP earn a median of $101,761 a year, 29.6% above the national figure of $78,538 and 72% above the $58,992 median for the 106 Maine 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 West Kennebunk CDP is valued at $514,700, 69.6% above the national figure and 132% above the $221,600 peer median, while median gross rent runs $1,426 a month, 1.4% above the national figure, or roughly $17,112 across a full year. A household on the local median income would put about 16.8% 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 5.1×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 70.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
