It can be tempting to think of "the uninsured" as the poorest of the poor. But that's not entirely the case. While people living below the poverty line are the most likely to be without health insurance, 28 percent of people who make between 100 and 200 percent of poverty level (up to about $23,340) lack coverage, as do 15 percent of those who make between 200 and 400 percent (up to about $46,700).
These maps, created by Kevin Johnson and used here with permission, show where people not covered by either private or public insurance live in each city. Johnson used the 2012 American Community Survey; higher uninsured rates are represented by red and orange colors.
Some of the maps do show a clear rich/poor divide, like this one of Oakland and San Francisco:
But in other areas, its neither the wealthiest nor poorest communities that have the highest uninsured rates. In 27 states, Medicaid covers adults at the lowest end of the economic spectrum, even if they don't have dependent children. So in many areas, the uninsured are those who are too rich for public assistance but aren't connected to coverage through work for whatever reason. (This is perhaps best represented in the Obama administration's recent beseeching #GeeksGetCovered so they can launch more startups.)
