Northfield, MA population, income and ZIP codes

Northfield CDP is a very small community in Massachusetts, with 908 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #228 of 248 ranked by population — larger than 8% of them. The median age here is 49.6 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 Northfield CDP earn a median of $74,875 a year, 4.7% below the national figure of $78,538 and 25% below the $99,537 median for the 222 Massachusetts 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 13.3% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Northfield CDP is valued at $279,300, 7.9% below the national figure and 44% below the $497,400 peer median, while median gross rent runs $1,071 a month, 23.8% below the national figure, or roughly $12,852 across a full year. A household on the local median income would put about 17.2% 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 3.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 76.6% 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.

With 908 residents, a handful of survey responses moves every median on this page. Compare Northfield CDP against its county rather than against national figures.

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.
