World population likely to peak by 2070
New population projections from IIASA researchers provide a fundamentally improved view of future population, structured by age, sex, and level of education, which differ from recent projections by the United Nations.
World population will likely peak at 9.4 billion around 2070 and then decline to around 9 billion by 2100, according to new population projections from IIASA researchers, published in a new book, World Population and Human Capital in the 21st Century. Alternative scenarios included in the projections range from 7 billion to almost 13 billion by 2100. The book will be officially launched today at an event at the Wilson Center in Washington DC.
More than just population numbers, the new book also includes specific projections for population by age, sex, and education level, for 195 countries in the world, from 2010 to 2100.
“This book presents the broadest ever synthesis of expert knowledge on drivers of fertility, mortality, migration and education in all parts of the world,” says Wolfgang Lutz, who led the project. Lutz is Director of IIASA’s World Population Program and Founding Director of the Wittgenstein Centre for Demography and Global Human Capital, a collaboration of IIASA, the Austrian Academy of Sciences, and the Vienna University of Economics.
