Immigration and Uninsured Rates

Ezra Klein posts a nifty chart showing the rate of uninsured over the past few years.  The chart debunks the notion that the uninsured rate has increased due to immigration issues.  He writes:

You occasionally hear conservatives argue that the problems of the uninsured in this country are entirely due to immigration. No immigrants, no increases in the uninsured. I've shot this point up before, but EPI helpfully graphed the debate, showing what would have happened to the population of the uninsured had immigration been frozen in 2000.

As you can see, freeze immigration and the 2.1% increase in the uninsured population becomes a...1.9% increase in the uninsured population. Which equals out to 5.7 million more Americans uninsured.
