There are two serious problems with the commonly-cited number of 47 million Americans without health insurance:

First, the "47 million" figure exaggerates the problem by a huge amount, as discussed in this short video, "Uninsured in America" as well as in numerous articles such as "The '47 Million' Uninsured Myth" in the August 29, 2007 issue of Investors Business Daily.

Second, it assumes the common error of equating health insurance with health care. The nature and significance of this error is covered in much more depth in the article co-author by Lin Zinser and myself, "Moral Health Care vs. 'Universal Health Care'".
