Increasing health care costs

Over the past 10 years the percentage of people who did not seek medical care because of costs has been rising, according to a recently released report by the CDC. This increase can not be explained because of aging, because the graph below is "age adjusted" and still shows this trend. There are a couple of other possible explanations, however. It might be that the percentage of people without insurance is increasing. Although this graph from the report suggests that the percentage of people without health insurance has been roughly flat over this period, the proportion insured among those age 18-64 has been declining (while the proportion of children insured has been increasing). Another possible explanation could be that health care costs have risen, or that other cost (like food and gas?) are on the rise, squeezing the family budget.

It also could be that we are just clumsier today than we were 10 years ago.
