Dunstable vs Groton
Dunstable and Groton are not two school districts that happen to look alike — they are one. Both are Groton-Dunstable, down to the same elementary buildings, so every school figure on this page is identical for the two. Schools cannot decide this one, which makes everything below the whole of it.
On tax, look past the rate: Dunstable works out roughly $3,000 a year cheaper on its own median 4BR.

Prices are estimates calibrated to the Zillow Home Value Index and Redfin; tax rates are FY2026 residential rates and the bill applies that rate to the town’s own median 4BR estimate; commutes take the rail leg from the MBTA timetable and still model the drive; rents are HUD FY2026 Small Area Fair Market Rents. School tiers are editorial and shown next to the state’s own MCAS figures. Data last reviewed — see the methodology. This comparison never uses demographics as an input.
