Key drivers

  • 2024 last-print persistence prior
  • ACTC phase-in beginning near the first earned dollar
  • Limited maximum gain of about $375 per phase-in-limited family
  • Low-income nonfiler take-up
  • Revised-SPM methodology transition

Resolution

source
U.S. Census Bureau revised-SPM methodology announcement (identity) and Poverty in the United States: 2027, Supplemental Poverty Measure Table B-2 (resolving artifact)
expected
December 31, 2028
rule
Resolve to the first Census annual income-and-poverty release artifact for CY2027 using the revised SPM methodology whose identity is authenticated by the registered 2026-07-17 Census announcement: Poverty in the United States: 2027, Supplemental Poverty Measure Table B-2, ALL RACES 2027 row, Under 18 years / Below Poverty / Percent column. The 2028-08-01 through 2028-12-31 expected release window and 2028-12-31 resolve-by deadline are Thesis lab commitments; the announcement does not establish either timing value. Record the published percent without scaling or rounding and ignore later revisions. If the conditioning legislation is not enacted by 2027-12-31, mark this conditional unresolved.
