And small increments increased the likelihood of problems.

There is a growing awareness at all levels of how broken our system is becoming. Health insurance is becoming increasingly unaffordable. The proposals that have dominated at the federal level are generally counterproductive, including health savings accounts.

The findings again call into question the whole approach of shifting more costs onto consumers with consumer-driven health care. If you look at a single mom with a kid at twice the poverty level and you look at the required deductible, it's already about 7.5 percent of income and that excludes the cost of the premium and other out-of-pocket costs.

The distinction between uninsured and insured isn't as simple as it used to be. When we look at people who are insured, we need to know not only if they have insurance, but do they have adequate insurance. So, the numbers could be misleadingly low.

This report does confirm and reinforce a lot of things that we know have been happening. One is that with insurance premiums continually going up at a rapid rate and coverage eroding, we're finding that even moderate- and middle-income families are starting to find insurance unaffordable, with the result that the number of uninsured in those groups is rising.
