A big reservation that many express over the size of the uninsurance problem in the U.S. is that often quoted 47 million figure. The argument is that the 47 million number includes a lot of people that some do not believe should be included – namely illegal immigrants, those that have money, and those that qualify, but are not enrolled in Medicaid. So the last post and the comments that followed addressed these issues, but I have one more argument to throw out there. I have to give credit to Paul Krugman for the numbers, but the argument goes like this. There are 47 million people who are uninsured, but that number is not static. Meaning that at any given time there are 47 million people (minus whoever you don’t think should be included) uninsured, but the people who make up that 47 million is constantly changing. Here is the number that Krugman introduced me to: One in every three Americans under the age 65 (non-Medicare) were uninsured at some point in either 2006 or 2007. That’s a large number. I’m sure it can be explained away or deconstructed, but it points to a truth that the number of Americans who are put at risk (financially or health-wise) is much larger than 47 million.
