One interesting thing about the economy is that relatively large numbers of people worked from their home: 10.62% of the workforce.

Other at-home workers may be self-employed people who operate small businesses out of their homes.

Groton, while not large, also appears to be attractive to some younger, educated professionals, who help shape the character of the town.
