Washington is a somewhat small borough located in the state of New Jersey. With a population of 7,335 people and two associated neighborhoods, Washington is the 255th largest community in New Jersey.

Telecommuters are a relatively large percentage of the workforce: 13.07% of people work from home. While this number may seem small overall, as a fraction of the total workforce it is high relative to the nation. These workers are often telecommuters who work in knowledge-based, white-collar professions. For example, Silicon Valley has large numbers of people who telecommute. Other at-home workers may be self-employed people who operate small businesses out of their homes.
