Jacksonville is a medium-sized city located in the state of Illinois. With a population of 17,279 people and six associated neighborhoods, Jacksonville is the 146th largest community in Illinois.

One interesting thing about the economy is that relatively large numbers of people worked from their home: 9.14% 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 Jacksonville is that there is very little traffic. The average commute to work is 17.61 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.
