October 8, 2026 — Marital-status research
Expanded the separately versioned research cohort to 7,745 observations across the United States, all 50 states and D.C., plus four counties and four cities. Authenticated Data Commons imports now supply the five-year history; 300 latest status counts and denominators match original Census tables. Searchable place selection and original Census one-year sex breakdowns accompany every supported profile. Inspect research release 2026-10-08-r2.
October 1, 2026 — Initial release
Published 5,237 observations across ACS, CDC/NCHS, Eurostat and ONS. Added a scoped Pew survey explainer and the first reproducible state comparison. The expanded r2 release adds five ACS measures (1,040 observations) without changing any r1 observations: recent reported marriages and divorces, current-marriage duration, and same-sex couple-household shares. The r3 source-note review preserves all estimates and adds CDC revision flags, population-basis footnotes and the Oklahoma cross-table coverage caveat.
