Princeton is a somewhat small city located in the state of Illinois. With a population of 7,721 people and three associated neighborhoods, Princeton is the 265th largest community in Illinois.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 7.78% 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 Princeton is that there is very little traffic. The average commute to work is 17.25 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.

In terms of college education, Princeton is somewhat better educated than the 21.84% who have a 4-year degree or higher in the typical US community: 27.07% of adults 25 and older in the city have at least a bachelor's degree.

The per capita income in Princeton in 2022 was $36,286, which is upper middle income relative to Illinois and the nation. This equates to an annual income of $145,144 for a family of four. However, Princeton contains both very wealthy and poor people as well.
