The Maine Health Care Access Foundation funded this profile of Maine health insurance coverage. According to data from the Current Population Survey, 124,000 Maine residents did not have health insurance during the 20042005 period. The majority (84%) of uninsured people were adults. Just over half of Maine residents who were uninsured came from low-income families residents. Low-income young adults (ages 1934) were particularly at risk for being uninsured, and one-quarter lacked coverage. Over 86,000 of Maine's uninsured people were workers. Forty-seven percent of this uninsured group were low-income, over half (55%) were employed by firms with fewer than 25 workers, and just over two-thirds worked in industries with low rates of job-based health coverage. Over two-thirds (67%) of Maine's uninsured people came from families with one or more full-time worker, while another 19 percent are from families with a part-time worker.
