Both parents now work full-time in most U.S. families for the first time

The Pew Research Center analysis of 2025 Census data directly supports the claim: 52% of different-sex couples with children under 18 now have two full-time working parents, a slim majority ('most') and a historical first, up from 31% in 1975. The Fortune article accurately relays this finding and frames it within affordability pressures, matching the claim's substance. One caveat: 'most U.S. families' is more precisely 'most different-sex couples with children under 18' (a slim 52% majority within that group), and 14% of working parents are unpartnered, so the headline simplifies the scope. Still, the core assertion is well supported by the primary source.
