In the 50 years since McKinsey Quarterly began publication, a rising economic tide has lifted much of the world. Each block in the chart below represents a country, with the block’s height indicating GDP per person and its width population. Not only has progress been widespread, but the world’s widest, most populous blocks—China and India—have become dramatically richer, with per capita wealth in China moving to more than $10,000, from roughly $600. On the far right of this economic map, US per capita GDP has increased to nearly $50,000, from roughly $20,000.
