Demography tools democratize futures

Simple, browser‑based population simulators let non‑experts run alternative demographic scenarios (fertility, mortality, migration) and immediately see effects on population size and age structure. They lower the barrier to testing assumptions behind official projections and reveal which parameters truly matter for long‑range planning. — Wider public access to sensitivity tools will shift debate from arguing about single official projections to contesting the assumptions that drive policy decisions on retirement, immigration, and public services.
