5% of Americans Made Up 50% of U.S. Health Care Spending

When it comes to America's spiraling health care costs, the country's problems begin with the 5%. In 2008 and 2009, 5% of Americans were responsible for nearly half of the country's medical spending.

Of course, health care has its own 1% crisis. In 2009, the top 1% of patients accounted for 21.8% of expenditures. 

The figures are from a new study by the Department of Health and Human Services, which examined how different U.S. demographics contributed to medical costs. It looked at the $1.26 trillion spent by civilian, non-institutionalized Americans each year on health care.
