There are over 7.5 million households in the U.S. in which the residents do not own an automobile. Of course, these homes rely on public transportation to commute to work, schools and shopping. Yet, 700,000 of those households don't even have access to public transit, according to the Brookings Institution. And for those with access, just over 40 percent of jobs in their metropolitan areas are accessible within 90 minutes. In some areas, it is much worse. 24/7 Wall St. identified the 10 metropolitan areas with the lowest rates of job access, as outlined in the Brookings report.
