Books by Warren C. Sanderson

Warren Sanderson and Sergei Scherbov argue for a new way to measure individual and population aging. Instead of counting how many years we've lived, we should think about our "prospective age"-the number of years we expect to have left. Their pioneering model can generate better demographic estimates, which inform better policy choices.

The 20th century was the century of explosive population growth, resulting in unprecedented impacts; in contrast, the 21st century is likely to see the end of world population growth and become the century of population aging. This book presents evidence about our demographic future and provides a framework for understanding the underlying unity.
