Does rising GDP per capita actually mean a better life for everyone?

This video examines the relationship between real GDP per capita and quality of life. While often dismissed as a measure of mere wealth, GDP per capita correlates with significant improvements in health, education, and happiness, making it a useful, though imperfect, tool for understanding human progress.

Real GDP per capita serves as a broad indicator of a nation's well-being, showing a consistent correlation with increased longevity, better educational outcomes, and rising incomes for the poorest citizens. It functions much like a thermometer, providing a quick, high-level reading of a country's economic state.

However, the metric has clear limitations regarding income distribution. For instance, Nigeria, Bangladesh, and Honduras share similar GDP per capita figures, yet Nigeria has a significantly higher proportion of its population living on less than $2 per day. Because it cannot account for how wealth is distributed among the population, GDP per capita remains an incomplete measure of a country's true standard of living.
