How are the IDBs estimates and projections calculated?
The IDB’s estimates and projections are prepared by Census Bureau demographers, who review a wide range of data, including censuses, surveys, and vital statistics provided by National Statistics Offices, and data on international migration and refugee movements. We also consider other information, such as public health efforts, socio-political circumstances, and historical events such as natural disasters and conflict. For additional information, please see our Population Estimates and Projections Methodology page.
