Telecommuters are a relatively large percentage of the workforce: 15.59% of people work from home. While this number may seem small overall, as a fraction of the total workforce it is high relative to the nation.

Other at-home workers may be self-employed people who operate small businesses out of their homes.

Chicago is one of the most attractive larger cities for people who are young, single, educated, and upwardly-mobile career starters.

In Chicago, however, the average commute to work is quite long. On average, people spend 34.71 minutes each day getting to work, which is significantly higher than the national average. One bright side is that local public transit is widely used, so it may be an option to avoid the headache of driving in the heavy traffic by leaving the car at home and taking transit. In addition, the city is also quite pedestrian-friendly, because many neighborhoods are very dense and have amenities close enough together that people find it feasible to get around on foot.

Chicago is a big city, and with that comes lots of benefits.

More than most large American cities, Chicago citizens use public transit daily to get to and from work. And while there are transportation options, most people in Chicago ride the bus. Whereas in some cities one is destined to sit in traffic every morning to get to work and every evening to get home, in Chicago a lot leave their cars at home (if they even choose to own one), and hop a ride on the bus.
