Greenfield is a medium-sized city located in the state of Massachusetts. With a population of 17,633 people and six associated neighborhoods, Greenfield is the 115th largest community in Massachusetts. Greenfield has an unusually large stock of pre-World War II architecture, making it one of the older and more historic cities.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 11.88% of the workforce. While this number may seem small overall, as a fraction of the total workforce this is high compared to the rest of the county. 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.

One of the benefits of Greenfield is that there is very little traffic. The average commute to work is 19.21 minutes, which is substantially less than the national average. Not only does this mean that the drive to work is less aggravating, but noise and pollution levels are lower as a result.

The citizens of Greenfield are very well educated compared to the average community in the nation: 39.15% of adults in Greenfield have a bachelor's degree or even advanced degree.

The per capita income in Greenfield in 2022 was $35,425, which is low income relative to Massachusetts, and middle income relative to the rest of the US. This equates to an annual income of $141,700 for a family of four. However, Greenfield contains both very wealthy and poor people as well.
