This is a cool map generated by Jim Gimpel, showing the distribution of the uninsured nationally.
He makes the point that:
The geographic concentration of the uninsured seems a bit ironic, given that the South and Southwest are not known for being Democratic strongholds agitating for a universal-coverage-single-payer system. But most of the uninsured fall heavily among the ranks of non-voters. The Republican congressional delegations from these states have little political incentive to work on this issue with President Obama. But the President doesn’t look like he needs them, either.Good point.
The thing that I find striking is how otherwise demographically different states can dramatically differ in their uninsured rates. Look at Iowa and Nebraska, or Minnesota and the Dakotas. Clearly there's some key difference in the laws and regulations of those states which makes it easier to be uninsured there. For that matter, Alabama and Mississippi are quite different as well, despite being comparable in other ways.
And what's up with Florida? For a relatively affluent state, it's almost as bad as Texas, despite having a far smaller illegal immigrant population.
I love maps.
