Caldwell is a somewhat small borough located in the state of New Jersey. With a population of 8,847 people and five associated neighborhoods, Caldwell is the 218th largest community in New Jersey.

Housing costs in Caldwell are among some of the highest in the nation, although real estate prices here don't compare to real estate prices in the most expensive communities in New Jersey.

Also of interest is that Caldwell has more people living here who work in computers and math than 95% of the places in the US.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 19.06% 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.

For a small borough, there is also a high proportion of single, often educated, people living in Caldwell. This is not typical for smaller communities in America, and adds a feeling of vibrancy to Caldwell.

One downside of living in Caldwell, however, is that residents on average have to contend with a long commute, spending on average 30.19 minutes every day commuting to work. It is, however, a pedestrian-friendly borough. Many of its neighborhoods are dense enough and have amenities close enough together that people find it feasible to get around on foot. In addition, local public transit is widely used. For those who would prefer to avoid driving entirely and leave their car at home, it may be an option to use the transit instead.

Despite being a small borough, Caldwell has a lot of people using the bus to get to and from work every day. Most of these people on the bus are using it to get to good jobs in other cities.

If knowledge is power, Caldwell is a pretty powerful place. 61.54% of the adults in Caldwell have earned a 4-year college degree, masters degree, MD, law degree, or even PhD. Compare that to the national average of 21.84% for all cities and towns.

The per capita income in Caldwell in 2022 was $60,262, which is upper middle income relative to New Jersey, and wealthy relative to the rest of the US. This equates to an annual income of $241,048 for a family of four.
