This reflects the reality that poverty reduction depends on inequality, both levels and changes, and sectoral and geographic patterns of growth. However, poor people are often not located where growth takes place (being in rural and fragile regions) and typically face constraints in moving to areas where growth is occurring. Further, political economy constraints within countries often hamper the implementation of policies of redistribution. However, unequal distribution of land ownership may constrain the poverty-reducing effect of agricultural growth.29 Similarly, since poor people usually have less skills, growth which expands sectors which use unskilled labor relatively intensively will be more poverty reducing than growth which expands other sectors. Empirical evidence from African countries supports the view that the structure of growth matters for poverty reduction.
