In 2018, the U.S. Centers for Disease Control and Prevention reported that "Medicaid was the source of payment for 43.0% of all births in 2017, an increase of 1% from 2016, and it increased for all maternal age groups." Medicaid, which was founded in 1965, is the main government healthcare program for low-income people. From 1966 to 2016, the average portion of the U.S. population receiving Medicaid benefits for the entire year increased from 2% in 1966 to 22% in 2016.
