One interesting thing about the economy is that relatively large numbers of people worked from their home: 14.56% 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.

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

In Leonia, however, the average commute to work is quite long. On average, people spend 31.41 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 borough 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.
