The impact of HIV/AIDS on Southern Africa's Children

6. Change in overall demographic profile of the region
 
Typically most developing countries have a population structure shape that can generally be described as a “pyramid”, a broad base that tapers off steadily with increasing age.

(Source: UNAIDS, June 2000).

As the HIV/AIDS epidemic begins to take its toll, the pyramid shape is being replaced by a “chimney” shape. The pyramid base becomes narrower, the female population above the age of 20 and the male population above the age of 30 shrinks radically. The exact implications of this new population structure are not clear (US Bureau of the Census, 2001; UNAIDS, 2000).
