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. 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.

Chicago is one of the most attractive larger cities for people who are young, single, educated, and upwardly-mobile career starters. This makes it a good place to live for young singles in their 20s and 30s and who have undergraduate or graduate degrees and are starting their professional careers. Although Chicago is a large city, this demographic is significant enough that young professionals will find many others like themselves here, with really good opportunities for friendships, recreation, romance, and more.

One downside of living in Chicago is that it can take a long time to commute to work. In Chicago, the average commute to work is 34.71 minutes, which is quite a bit higher than the national average. On the other hand, local public transit is widely used in the city, so leaving the car at home and taking transit is often a viable alternative. In addition, it is also a pedestrian-friendly city. Many of Chicago’s neighborhoods are dense enough and have amenities close enough together that people find it feasible to get around on foot.

One of the benefits of being a big city like Chicago is having a public transportation system, but in Chicago the transit system is the mode of choice for lots of people getting to and from work every day. You will find many people using the bus for their daily commute, even though other transportation options exist. If you ask these commuters, many will tell you that not having to drive in the snarl of big city traffic is one of main reasons for leaving the car at home, or even not owning a car at all. With so many people taking the bus Chicago benefits from a reduction in air pollution and traffic.
