Ayer CDP, MA in context

How this area compares with national benchmarks.

Ayer CDP is a small town in Massachusetts, with 3,012 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #154 of 248 ranked by population — larger than 38% of them. The median age here is 48 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 Ayer CDP earn a median of $81,286 a year, 3.5% above the national figure of $78,538 and 18% 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 9% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Ayer CDP is valued at $417,300, 37.5% above the national figure and 16% below the $497,400 peer median, while median gross rent runs $1,228 a month, 12.7% below the national figure, or roughly $14,736 across a full year. A household on the local median income would put about 18.1% 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. 61.8% 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.
