Thanks Gary,
It is interesting that demographers puts the decline in birth rates down to better medical treatment , vaccination and family planning in places such as Bangladesh where the rate has fallen to around 2. People are happier to have smaller families and not suffer the agonies of loss. Perhaps Africa will discover this sooner than we think.

A fertility rate of 2.1 births per woman is need to ensure population replacement and avoid declines, according to the report.
The new population projections indicate that nine countries will be responsible for more than half the projected population growth between now and 2050.
In descending order of the expected increase, they are: India, Nigeria, Pakistan, Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States.
In sub-Saharan Africa, population is projected to nearly double by 2050, where the fertility rate is 4.6 births per woman.
Between 2019 and 2050 populations are projected to decrease by one percent or more in 55 countries or areas, of which 26 may see a reduction of at least 10 percent.
In China the population is projected to decrease by 31.4 million, or around 2.2 percent, between 2019 and 2050.
