Mississippi has not expanded Medicaid, so the federal work requirement that takes effect January 1, 2027 does not apply to a state expansion population. This model counts no Mississippi adults as subject.
The requirement matters for Mississippi in a different way: if the state expanded Medicaid later, its expansion adults would report from day one. The American Community Survey counts about 307,875 uninsured Mississippi adults with household income at or below 138% of the poverty line, the population an expansion would cover and the requirement would then reach.

State brief and methodology
Estimates, not counts. The model rakes to CBO's national subject total and allocates by ACS microdata; state agencies hold the administrative data that would replace these figures.
