Fact check: What percentage of Walmart employees qualify for Medicaid?
Executive Summary
Existing materials do not provide a single authoritative percentage for how many Walmart employees qualify for Medicaid; the available studies and reports point to substantial overlap between low-wage retail employment and Medicaid enrollment but stop short of reporting a Walmart-specific share. The evidence indicates that Walmart openings and operations are associated with increased local poverty and higher Medicaid expenditures per worker, while Medicaid expansion enrollments include large numbers of private-sector and retail workers — suggesting a meaningful, but unquantified, share of Walmart employees likely qualify for Medicaid [1] [2] [3].
1. Why there is no single definitive answer and what the studies actually say about Walmart and low-income coverage
No study in the provided set gives a direct percentage of Walmart employees who qualify for Medicaid; instead, researchers analyze related outcomes like poverty changes near Walmart openings and Medicaid spending linked to Wal‑Mart employment. One paper finds Walmart Supercenter openings are associated with a 2 percentage point increase in poverty, implying that Walmart’s labor-market effects can push more workers toward means-tested programs, but it does not tabulate employer-specific Medicaid eligibility rates [1]. Another academic analysis estimates Walmart raises Medicaid expenditures by roughly $898 per worker, which signals a sizable public cost tied to the company’s wage and benefits profile without converting that cost into a precise enrollment share [2]. Both pieces imply material interaction between Walmart employment and Medicaid reliance, but neither supplies a single percent figure for Walmart employees.
2. What Medicaid expansion data tell us about retail and private-sector workers who enroll
State-focused expansion analyses reveal that many Medicaid expansion enrollees are in payroll jobs and in retail or accommodation sectors, which is directly relevant because Walmart is a major private-sector employer in retail. For example, Montana’s 2023 data show 94,990 expansion enrollees with payroll jobs, equal to 16% of private-sector employees, and that 72% of accommodation and food services businesses and 52% of retail businesses employed at least one expansion-enrolled worker [3]. Those figures demonstrate that expansion disproportionately covered working, low-wage employees in retail industries. The implication is that a nontrivial fraction of workers at large retail employers like Walmart likely qualify for Medicaid where income thresholds and state expansion status permit, yet the data stop short of attributing enrollment to any specific employer.
3. How researchers infer employer-level impacts without employer-specific enrollment data
Researchers often rely on quasi-experimental approaches—comparing areas before and after Walmart openings or exploiting variation from Medicaid expansion—to estimate how employers affect public coverage and expenditures. The Walmart opening studies and expenditure analyses use geographic and administrative variation to tie broader public-cost changes to Wal‑Mart presence, revealing increased poverty and higher Medicaid spending per worker [1] [2]. These methods expose causal links between large retail employers and public insurance burdens, but they cannot translate area-level or per-worker spending effects into an employer-specific enrollment share without matched employer-employee Medicaid records. Thus, the existing literature is informative about scale and direction but not definitive about the percent of Walmart employees who meet Medicaid eligibility criteria.
4. Diverging viewpoints and potential agendas in interpreting the evidence
Different stakeholders use these findings to advance contrasting narratives. Labor advocates emphasize the poverty and public-cost effects tied to Walmart as evidence of inadequate wages and benefits, citing the 2-point poverty rise and higher Medicaid expenditures as markers of corporate social externalities [1] [2]. Business-friendly analysts may highlight that Medicaid expansion covers many working people across retail and accommodation sectors irrespective of employer and argue that public-policy choices (state expansion, eligibility rules) drive enrollment more than any single firm [3]. Both perspectives rest on the same empirical building blocks but prioritize different causal levers: employer pay practices versus state-level Medicaid policy. The reviewed sources show both narratives are supported by data but neither produces a Walmart-specific enrollment percentage.
5. What would be required to produce a precise percentage and why it matters for policy
A precise percentage would require matched administrative records linking Walmart payroll/employment files to Medicaid enrollment data or a representative survey with employer identifiers and income/household composition. That linkage would allow a clear count of which Walmart employees meet income and categorical eligibility across states and months. The absence of such linked data means policymakers must rely on indirect but consistent evidence that many retail workers are covered by Medicaid or expansion programs. For policy debates about employer responsibility, public costs, or minimum-wage effects, knowing an exact percentage matters; however, the current literature strongly indicates a meaningful share of retail workers — and plausibly a considerable share of Walmart employees — qualify for Medicaid even though a precise employer-specific figure is not reported [1] [2] [3] [4] [5].
