The spatial concentration of the poorest in regions within countries is a persistent and increasing feature of income inequality in many countries. High and rising spatial inequalities pose a significant development challenge. What types of policies effectively address these inequalities? Should we invest more in the places where the poor concentrate, or in the places that create jobs? When investing in lagging regions, what types of investment should be made? What are the factors that determine what the appropriate strategy should be?
