On the contribution of sectoral natural population growth to the aggregate poverty change

This note extends the Ravallion and Huppi (World Bank Econ Rev 5(1):57-82, 1991) aggregate poverty change decomposition to account for the distinct contribution of migration and differential natural population growth between sectors to the aggregate poverty change. We apply our decomposition to three Least Developing countries. We find that accounting for sectoral difference in natural population growth has a considerable impact on national poverty change.
