East Merrimack, NH population, income and ZIP codes

East Merrimack CDP is a small town in New Hampshire, with 4,872 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #28 of 100 ranked by population — larger than 72% of them. The median age here is 41.8 years against 39.1 nationally, a slightly older 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 East Merrimack CDP earn a median of $82,829 a year, 5.5% above the national figure of $78,538 and 7% above the $77,368 median for the 65 New Hampshire 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 6.9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in East Merrimack CDP is valued at $267,900, 11.7% below the national figure and within a couple of points of the $271,300 peer median, while median gross rent runs $1,780 a month, 26.6% above the national figure, or roughly $21,360 across a full year. A household on the local median income would put about 25.8% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 3.2×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 67.4% 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.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
