Inequality is the uneven distribution of income, wealth, power, or opportunities among individuals or groups within a society. Inequality can result from various factors, such as market forces, institutions, policies, norms, or preferences. Inequality can have different dimensions, such as income inequality, wealth inequality, gender inequality, racial inequality, or spatial inequality. Inequality can also have different effects, such as reducing social mobility, increasing poverty, undermining social cohesion, or lowering economic growth.
