Rising inequality is a global trend that has negative economic and social consequences. While inequality has increased almost everywhere, there are some regional variations. Absolute inequality, which measures the actual income or wealth difference between groups, has risen nearly everywhere. Relative inequality, which measures the ratio of incomes between groups, has declined in some places. Within countries, rising inequality is now the main driver of increased global inequality. High and rising inequality can undermine economic growth, increase economic insecurity, weaken social cohesion and democracy, and threaten multilateral cooperation. Addressing inequality is important to create a more stable global economic and political environment.
