About our project

The overarching goal of the BayesPop working group is to develop a statistical framework for probabilistic population projections for all countries. On July 11, 2014 (World Population Day), the United Nations issued official probabilistic population projections for all countries for the first time, using our new statistical methods. A previous experimental version had been issued by the UN in November 2012. Population projections have long been done in a deterministic way, and this is a major step towards putting them on a statistical and probabilistic basis.

The specific aims of our further research are:
  • Developing methods for probabilistic projection of correlated population quantities
  • Developing methods for probabilistic projections of international migration
  • Developing methods for age-specific probabilistic projections
  • Probabilistic projections for countries with generalized HIV/AIDS epidemics
  • Developing methods for reconstructing past populations with uncertainty from fragmentary data
  • Producing publicly available software that implements the new methods
