"Personal consumption" is a comprehensive measure of the goods and services consumed by people. It is the World Bank's "preferred" indicator of material well-being due to "practical reasons of reliability and because consumption is thought to better capture long-run welfare levels than current income." The latest available data show that the United States has the highest average consumption per person of all nations in the world. The U.S. lead is so great that even the poorest 20% of people in the U.S. consume more goods than the national averages for ALL people in most developed countries.
