In Texas, 24 percent of people are uninsured, according to figures collected by the Kaiser Family Foundation, in a  report and graphic based on 2011 figures.

Next: Nevada 22 percent, New Mexico 21 percent. South Carolina, Florida, Georgia, California and Louisiana all have 21 percent of people lacking insurance.

Mississipi: 19 percent.

Alaska, Montana, Idaho, Arkansas, Wyoming, Arizona: All 18 percent.

That’s a lot of uninsured people. So what does this mean for the implementation of the Affordable Care Act? it’s not clear: How many of those uninsured people will choose to buy insurance? What will it cost them, and will they receive subsidies, take the penalty for being uninsured? It’s an open question.

Massachusetts, not surprisingly, is at 4 percent.

Almost as interesting is the rate of people enrolled in Medicaid, for low-income people. New Hampshire is lowest at 7 percent, while the District of Columbia and Vermont are tied at 24 percent of population. Maine, New Mexico and New York follow at 22 percent of population.

Individual insurance? Montana and North Dakota lead at 9 percent of population.
