“Examining age across childhood and young adulthood, uninsured rates in 2017 were generally lower for children than for young adults, from 3.5 percent for infants to 17.8 percent for 26-year-olds. Two sharp differences existed between single-year ages. The percentage of 19-year-olds without coverage (13.2 percent) was 4.6 percentage points higher than the percentage for people 1 year younger. Likewise, the uninsured rate for 26-year-olds, the highest among all single years of age in 2017, was distinctly higher than for 25-yearolds (17.8 percent and 14.9 percent, respectively).

“From ages 26 to 64, the uninsured rate generally declined with age. Between the ages of 64 and 65, the uninsured rate then decreased 4.9 percentage points. In 2017, 6.6 percent of 64-year-olds and 1.6 percent of 65-year-olds did not have health insurance coverage. For adults aged 65 and over, the uninsured rate varied little by age.

“Between 2016 and 2017, the percentage of people without health insurance coverage at the time of interview did not statistically change for most single years of age. However, for children under the age of 19 and working -age adults between 50 and 59, the uninsured rate increased across multiple single years of age.”
