City maps from the Robert Wood Johnson Foundation reveal the wide discrepancies in life expectancy that can be plotted within a small area. Just a few miles can mean a 13-year difference in life expectancy for babies born in Minneapolis and St. Paul. Socioeconomic differences have shown that being rich helps you live longer, and vice versa. But these maps reveal vast gaps just by comparing neighborhoods. The Minnesota map is below, and the foundation plotted life expectancy in other metro areas here. "Where we live, learn, work and play can have a greater impact on our health than we realize," the foundation said.
