Fertility dashboard as fiscal early‑warning

Treat openly published national fertility time series (UN/World Bank) as an institutional early‑warning metric that should automatically trigger fiscal and labor‑market stress tests (pensions, schooling, immigration policy). Public agencies could pair year‑on‑year fertility declines with simple thresholds (e.g., sustained <2.1 over X years) to prompt concrete planning steps. — Turning fertility data into automated fiscal and labor stress tests would move demographic forecasting from esoteric research into routine public policy triggers with concrete budgetary consequences.
