Changes in economic conditions and health insurance coverage, 2000-2004.

Between 2000 and 2004, the number of uninsured Americans increased by six million, primarily because of a decline in employer-sponsored insurance. All of the increase occurred among adults, for whom the drop in employer coverage was not offset by an increase in public coverage. The number of uninsured children fell slightly. About two-thirds of the growth in the uninsured was among Americans below 200 percent of the federal poverty level. Coverage rates have also fallen among higher-income Americans. About half of the growth in the uninsured was among young adults ages 19-34, about 55 percent among whites, and 73 percent among native-born citizens.
