If the Trump administration’s proposed 2018 budget were to be fully adopted, federal spending on children would be at least 9 percent lower over the 10-year budget window compared with projections under current law. The largest proportional cuts would be to spending on education programs, which would be reduced by 15 percent below baseline spending projections for 2018–27. SNAP, Medicaid, and TANF would also experience substantial cuts, and some housing and social services programs would be eliminated entirely. The brief builds off the Urban Institute’s annual Kids’ Share reports, which track government spending on children annually and current-law projections.
