A relatively large number of people in Seabrook telecommute to their jobs. Overall, about 10.55% of the workforce works from home. While this may seem like a small number, as a fraction of the total workforce it ranks among the highest in the country.

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