Religious Demographics Reorder Politics

Pew’s global projections show predictable shifts in the size and age structure of religious groups (for example, faster Muslim population growth driven by younger age profiles and higher fertility). These changes will alter local and national constituencies, influence migration politics, and reshape policy debates over the next decades. — If true, shifting religious shares will change voting blocs, immigration pressures and foreign‑policy constituencies, making demographic forecasts a crucial input for political strategy and public policy.
