Elmer is a very small borough located in the state of New Jersey. With a population of 1,368 people and three associated neighborhoods, Elmer is the 460th largest community in New Jersey. Elmer has an unusually large stock of pre-World War II architecture, making it one of the older and more historic boroughs.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 10.49% 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.

As is often the case in a small borough, Elmer doesn't have a public transportation system that people use for their commute.

In terms of college education, Elmer is somewhat better educated than the 21.84% who have a 4-year degree or higher in the typical US community: 25.41% of adults 25 and older in the borough have at least a bachelor's degree.

The per capita income in Elmer in 2022 was $42,084, which is lower middle income relative to New Jersey, and upper middle income relative to the rest of the US. This equates to an annual income of $168,336 for a family of four.
