Health insurance coverage for young adults.

Given that such a large and growing share of young adults ages 19 to 26 lacks health insurance coverage, increasing policy attention has been focused on addressing coverage gaps among young adults. Fully 10.3 million young adults—or one in three (32 percent)—lack health insurance coverage. While young adults constitute 18 percent of the adult population, they make up 28 percent of the uninsured adult population (Exhibit 1). Almost half (49 percent) have employer-sponsored insurance (ESI) coverage, 10 percent have Medicaid/other public coverage, and 10 percent have non-group coverage (Exhibit 2).
