Instead, it has a mixed workforce of both white- and blue-collar jobs. Overall, Philadelphia is a city of professionals, service providers, and sales and office workers. There are especially a lot of people living in Philadelphia who work in office and administrative support (11.08%), management occupations (9.10%), and sales jobs (7.87%).

A relatively large number of people in Philadelphia telecommute to their jobs. Overall, about 13.84% of the workforce works from home. While this may seem like a small number, as a fraction of the total workforce it ranks among the highest in the country.

Other at-home workers may be self-employed people who operate small businesses out of their homes. One downside of living in Philadelphia is that it can take a long time to commute to work.

The benefits include reduced air pollution and load on the road network.The overall education level of Philadelphia citizens is substantially higher than the typical US community, as 33.61% of adults in Philadelphia have at least a bachelor's degree, and the average American community has 21.84%.
