One interesting thing about the economy is that relatively large numbers of people worked from their home: 10.26% 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 downside of living in Roselle is that it can take a long time to commute to work. In Roselle, the average commute to work is 33.39 minutes, which is quite a bit higher than the national average. On the other hand, local public transit is widely used in the borough, so leaving the car at home and taking transit is often a viable alternative. In addition, it is also a pedestrian-friendly borough. Many of Roselle’s neighborhoods are dense enough and have amenities close enough together that people find it feasible to get around on foot.
