Congressional District Interactive Map: Medicaid Enrollment by Eligibility Group

There are several options under consideration in Congress to significantly reduce Medicaid spending to help pay for tax cuts, with the recently passed House budget resolution targeting cuts to Medicaid of up to $880 billion or more over a decade. Medicaid is the primary program providing comprehensive health and long-term care to 83 million people living in the U.S (particularly those with low-incomes) and accounts for nearly $1 out of every $5 spent on health care. Medicaid is administered by states within broad federal rules and jointly funded by states and the federal government, meaning restrictions in federal Medicaid spending could leave states with tough choices on how to offset reductions through cuts to Medicaid, cuts to other programs, or tax increases.

In the months ahead, members of Congress will be considering and voting on various proposals to cut the Medicaid program. President Trump and Speaker Johnson have promised to leave Medicaid intact, cutting only fraud, waste, and abuse. However, if Medicaid is cut by $880 billion over 10 years, that would reduce federal spending by 13% relative to KFF’s projections of Medicaid spending under current law (which estimate spending growth using the Congressional Budget Office’s Medicaid projections). Cuts of that magnitude would force states to raise new revenues or reduce Medicaid spending by eliminating coverage for some people, covering fewer services, or cutting payment rates for providers.

The interactive maps below illustrate how many people are enrolled in Medicaid and what percentage of the population is enrolled in Medicaid for each congressional district. Enrollment numbers include enrollment in each of the major Medicaid eligibility groups, highlighting whose coverage may be at risk in upcoming deliberations. Key takeaways include:

• There are 53,000 or more Medicaid enrollees living in each congressional district, with enrollment as high as 510,000 in some districts. In each congressional district, there are at least: 3,500 Medicaid enrollees ages 65 and older, 2,000 enrollees eligible because of a disability, 7,400 child enrollees, and 5,300 other adult enrollees.
• In half of all Republican congressional districts, 21% or more of the population is enrolled in Medicaid; and in half of all Democratic districts, 26% or more of the population is enrolled in Medicaid.
• Republican districts have a higher share of Medicaid enrollees who are children and who are eligible because of a disability compared with Democratic districts that have a higher share of expansion enrollees and adults ages 65 and older.
• The top 10 Republican districts with the highest number of Medicaid enrollees are: CA22 (495,200); KY05 (397,800); CA23 (355,400); CA01 (316,800); LA05 (312,600); NY11 (304,100); LA03 (303,000); WV01 (300,100); LA04 ( 288,400); and WA04 (278,000).
• The top 10 Democratic districts with the highest number of Medicaid enrollees are: NY15 (510,100); CA43 (473,500); CA37 (470,600); CA21 (462,900); CA34 (453,800); NY13 (426,200); NY14 (423,800); CA13 (417,800); AZ03 (410,900) and CA25 (397,400).
