The Census Bureau is out with a new report on insurance coverage. What makes the Small Area Health Insurance Estimates report different from others is that it's got data on the county level.
There's a number of articles out now about how many people don't have health insurance. For example, see stories from Colorado, Hawaii, Utah, and Wisconsin.
The Kaiser Health Policy Daily Report notes that "previous data gathered in 2000 were not applicable because the researchers used a different method to gather the data in 2005."
