measuring international and global inequality
Inequality has increased between nations over the last half century (richer countries have generally grown faster than poorer countries). And yet the two most populous nations, China and India, have also grown fast. But over the past two decades inequality within countries has increased. As complex as reconciling these three data trends may be, it is clear: the inequality between the world's individuals is staggering. At the turn of the twenty-first century, the richest 5 percent of people receive one-third of total global income, as much as the poorest 80 percent. While a few poor countries are catching up with the rich world, the differences between the richest and poorest individuals around the globe are huge and likely growing.
