Notes on verification
Directly confirmed by the NBER working paper abstract and consistent across multiple independent versions (Census Bureau, Yale Cowles Foundation, author site) plus corroborating media coverage quoting the lead author. [tier=silver indep_score=0.925 clusters=2 claim_tier=notable]
