"Despite encouragement for sustainable commuting, fewer urban Americans than ever are taking public transportation to work," writes Mary Jander.
"This is a recent finding of the US Census Bureau's American Community Survey. In 2012, just 11 percent of employed Americans age 16 or over who lived in communities with populations of more than 65,000 reported taking the bus, train, or other public conveyance to work... More people are driving alone now than in 2008. Carpooling, once touted as a way to save fuel and costs, has dropped accordingly."
