Decades are framed 1976–1985 · 1986–1995 · 1996–2005 · 2006–2015 · 2016–2026. Every 50-yr trend is a real, sourced national series. Pima-specific health and economic figures (from the PHIT Score Card / Census) are current values, not 50-year county series — no agency publishes those back 50 years — so we pair the national trend with Pima's Pima now point. Two series carry notes: intimate-partner violence is nationally comparable only from 1993, and maternal mortality's comparable NCHS series begins 2018. County-level turnout by age/gender is not published below the national level. Nothing here is an invented trend.
