Demographics & Population Health
Wealth, health, and population size, all at once — the same three-variable view that made Hans Rosling's Gapminder famous, rebuilt here on current data — plus how the world's population has grown and shifted across regions over the last seven decades.
Wealth & Health of Nations
Each bubble is a country · x = GDP per capita (log scale) · y = life expectancy · size = population · click a legend item to isolate a region. Notice how tightly life expectancy tracks income at the low end, then flattens out — past a certain point, more GDP buys progressively less extra longevity.
Bubble area (not radius) scales with population. Color capped to three regions plus "Other" for reliable distinction.
World Population Growth
Midyear estimate, 1950 to present — growth is slowing even as the total keeps climbing
Population by Region Over Time
Stacked by continent — Asia and Africa account for almost all of the growth in this chart
