TL;DR: World population is likely to continue growing for the rest of the century, with at least a 3.5-fold increase in the population of Africa and the ratio of working-age people to older people is almost certain to decline substantially in all countries, not just currently developed ones.
Journal ArticleDOI
A universal pattern of mortality decline in the G7 countries.
TL;DR: This paper examined mortality over five decades in the G7 countries (Canada, France, Germany, Italy, Japan, UK, US) and found that mortality at each age has declined exponentially at a roughly constant rate.
Journal ArticleDOI
Coherent mortality forecasts for a group of populations: an extension of the Lee-Carter method.
Nan Li,Ronald Lee +1 more
TL;DR: Using the Human Mortality Database, the Lee-Carter model is applied to a group of populations, allowing each its own age pattern and level of mortality but imposing shared rates of change by age.
Journal ArticleDOI
Bayesian probabilistic population projections for all countries
TL;DR: The results suggest that the current United Nations high and low variants greatly underestimate uncertainty about the number of oldest old from about 2050 and that they underestimate uncertainty for high fertility countries and overstate uncertainty for countries that have completed the demographic transition.
