Medicare and Medicaid are the two largest healthcare programs in the United States.

Approximately 57 million people received coverage from Medicare plans in 2016, while Medicaid had about 66 million enrollees in 2018.

Medicare is the federal health insurance program that supports certain groups of people, including those who are 65 years or older, those with permanent kidney failure, and some younger people with disabilities.

Medicaid is a federal and state program that helps people who have limited income and resources.

Medicare accounted for 15 percent of the federal budget in 2017. As the population ages and healthcare costs rise, experts estimate that healthcare spending will continue to grow. According to projections, Medicare spending will reach 18 percent by 2028.
