Our demographic future: predictions for the next 50 years.

"This special issue of Population Today commemorates one-half century of the Population Bulletin by looking one-half century into the future. We asked experts and advocates for their predictions: What will be the most important demographic development in the next 50 years? The people we asked ranged from well-known leaders in the field to young people just starting out.... We at PRB hope that this special feature will stimulate thought about our world's future, as viewed through the lens of demography."
