| description | This paper reviews historical and projected trends in world population numbers, and the underlying determinants of those trends. Whereas the world's population has shown little change over most of its one million-year history, the past 200 years have witnessed dramatic changes in fertility, mortality and population growth rates. Recent decades, in particular, have seen unprecedented demographic events, with more people added to the world's population in the past 50 years than in the preceding million. The demographic impact of HIV/AIDS, selective as it is to young adults and infants, is also unprecedented, with life expectancy among some populations reduced by almost 20 years. As we approach the end of the 20th century, further demographic changes are underway with, for the first time in recent human history, a slowing down of world population growth. Nonetheless, world population is projected to grow from 6 billion currently to about 9.4 billion by 2050 (medium fertility assumption), with ageing emerging as the most pressing demographic issue facing humanity in the millenium. |
