Groton, MA population, income and ZIP codes

Groton CDP is a small town in Massachusetts, with 1,571 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #207 of 248 ranked by population — larger than 16% of them. The median age here is 29.3 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 Groton CDP earn a median of not published a year. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 7.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Groton CDP is valued at $736,800, 142.8% above the national figure and 48% above the $497,400 peer median, while median gross rent runs not published a month. 65.6% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.

A median age of 29.3 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address.

The Census withheld household income, gross rent for Groton 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.
