Using World Bank PovcalNet data from \n 1974-2018 for 135 countries, this paper approximates the \n identity that links growth in mean incomes and changes in \n the distribution of relative incomes to reductions in \n absolute poverty, and, in turn, examines the role of income \n inequality for poverty reduction. The analysis finds that \n the assumption that income is log-normally distributed \n allows one to approximate the identity well. Using this \n approximation, both the growth and inequality elasticities \n of poverty reduction are calculated. The inequality \n elasticity of poverty reduction is larger, on average, \n compared to the (absolute) growth elasticity of poverty \n reduction. Moreover, the (absolute) growth elasticity \n declines steeply with a country's initial level of \n inequality. However, despite these results, most of the \n observed changes in poverty can be explained by changes in \n mean incomes. This is a consequence of changes in income \n inequality (as measured by percentage changes in the \n standard deviation of log-income) being an order of \n magnitude smaller than changes in mean incomes. Overall, the \n results highlight the important role income inequality can \n play in reducing poverty even if prior poverty changes have, \n in large part, been a consequence of economic growth
