The UN recently issued official probabilistic population projections for all countries for the first time, using a Bayesian hierarchical framework developed by our University of Washington group. These take account of uncertainty about future fertility and mortality, but not international migration. Raftery proposes a Bayesian hierarchical autoregressive model for projecting migration rates for all countries, broken down by age and sex. Raftery resolve a paradoxical discrepancy between growth trends in the proportion of the world population migrating and the average absolute migration rate across countries.
