Comparative Analysis
Compare how technology adoption unfolded across countries. Select any combination of countries and metrics to overlay their diffusion trajectories against the Rogers reference curve.
How to Read S-Curves
Each colored line traces a country's adoption from 1960–2023. The dashed grey curve is the theoretical Rogers S-curve. Steeper curves = faster adoption. Countries starting later but rising quickly show leapfrogging. Use the dropdown to switch metrics and + Add Country to compare nations (enter ISO codes like USA, CHN, IND, NGA, BRA, DEU, KEN, KOR, GBR, etc.).
