To create an accurate population forecast, a forecaster can use a myriad of different methods to assemble his or her data. The transparency of the forecaster’s data and methods is essential, and the forecaster must be able to argue for and explain their assumptions. In this useful book, Joop de Beer specifically investigates how a population’s fertility, life expectancy, and migration patterns can be used to shape a population forecast. He also shows how comparative data, such as the difference between longevity in Europe and Japan, can be helpful when creating population projections. 

Joop de Beer is head of the Department of Population Dynamics at the Netherlands Interdisciplinary Demographic Institute.
