Fairhaven is a medium-sized coastal town (i.e. on the ocean, a bay, or inlet) located in the state of Massachusetts. With a population of 15,837 people and four associated neighborhoods, Fairhaven is the 128th largest community in Massachusetts. Fairhaven has an unusually large stock of pre-World War II architecture, making it one of the older and more historic towns.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 9.08% 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 nice things about Fairhaven is that it is nautical, which means that parts of it are somewhat historic and touch the ocean or tidal bodies of water, such as inlets and bays. Because of this, visitors and locals will often go to these areas to take in the scenery or to enjoy waterfront activities.

The education level of Fairhaven citizens is substantially higher than the typical US community, as 29.57% of adults in Fairhaven have at least a bachelor's degree.

The per capita income in Fairhaven in 2018 was $54,224, which is middle income relative to Massachusetts, and wealthy relative to the rest of the US. This equates to an annual income of $216,896 for a family of four. However, Fairhaven contains both very wealthy and poor people as well.
