Q. Let’s get inside those rough numbers. Who tends to be uninsured?

A. They tend to be younger, with those most likely to be uninsured between ages 19 and 24. Almost all adults age 65 and above are covered primarily by Medicare, and many of them have supplemental private insurance.

Men are a little bit more likely to be uninsured. Married individuals and persons with more than a high school education are much more likely to be insured.

Most of the uninsured (88 percent) are in good to excellent health. The likelihood of being insured rises with income and full-time work status, although nearly half (47 percent) of the uninsured are full-time workers.

Hispanics are considerably more likely than those in any other ethnic category to be uninsured (over 30 percent).

More than a quarter of the uninsured are foreign-born. By Census Bureau estimates, about 10 million uninsured are not citizens and half of them are illegal immigrants.
