While men were most likely to be in the middle age groups (40-59 years), women were younger with a higher distribution in age groups 20-29 and 30-39 years.

Note that people age 65 and older may have switched from Medicaid to Medicare or have had both insurance plans. For dually-enrolled patients Medicare pays for most health care services and Medicaid pays for long-term care and home health care services.
