Demographic trends and domestic economic stability
Demographic trends—chiefly declining fertility rates, population aging, and shifting dependency ratios—are major drivers of domestic economic stability. These changes influence labor supply, potential GDP growth, fiscal balances, consumer demand, and long-term productivity. While they create headwinds in many economies, outcomes depend heavily on policy responses. Below is a data-driven overview based on recent projections (as of early 2026). Core Global and Regional Demographic Trends Fertility rates have fallen sharply worldwide. The global total fertility rate (average children per woman) dropped from over 5 in the 1960s to around 2.25–2.3 today, hovering just above the replacement level of 2.1 needed for a stable population (absent migration). In more than half the world’s countries—home to two-thirds of humanity—rates are already below replacement, with “ultra-low” levels (under 1.4) in places like South Korea, Italy, Spain, and China.
