South Ashburnham, MA population, income and ZIP codes

South Ashburnham CDP is a small town in Massachusetts, with 1,174 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #219 of 248 ranked by population — larger than 11% 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 South Ashburnham CDP earn a median of $82,006 a year, 4.4% above the national figure of $78,538 and 18% below the $99,537 median for the 222 Massachusetts 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 16% of residents here, above the 12.4% national rate.

The typical owner-occupied home in South Ashburnham CDP is valued at $323,400, 6.6% above the national figure and 35% below the $497,400 peer median, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.9×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 85% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

The Census withheld gross rent for South Ashburnham CDP because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.
