The UN projects an increase in world population of 4 billion people – from 7 billion to 11 billion – between 2010 and 2100. In this April 10, 2017 presentation at Institut National d’Études Démographiques (INED), David Lam explores the demographic, economic, and regional dimensions of this projected growth and compares it to the previous world population growth of 4 billion people from 1960-2010.
