Salem is a somewhat small coastal city (i.e. on the ocean, a bay, or inlet) located in the state of New Jersey. With a population of 5,324 people and five associated neighborhoods, Salem is the 305th largest community in New Jersey. Salem has a large stock of pre-World War II architecture, making it one of the older and more historic cities in the country.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 11.74% 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 Salem 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.

Despite the fact that it is a small city, Salem has quite a few people who take public transportation – mostly the bus - for their daily commute to work. This helps to fill a real need in the city for affordable transportation.

The percentage of people in Salem with college degrees is quite a bit lower than the national average for cities and towns of 21.84%: just 11.29% of people over 25 have a bachelor's degree or advanced degree.

However, Salem contains both very wealthy and poor people as well. Salem also has one of the higher rates of people living in poverty in the nation, with 31.63% of its population below the federal poverty line.
