A report on Population ageing

Median age by country.
Percentage of world population over 65
This map illustrates global trends in ageing by depicting the percentage of each country's population that is over the age of 65. The more developed countries also have older populations as their citizens live longer. Less developed countries have much younger populations. An interactive version of the map is available here.

Increasing median age in a population because of declining fertility rates and rising life expectancy.

A major factor in reducing birth rates in stage 3 countries such as Malaysia is the availability of family planning facilities, like this one in Kuala Terengganu, Terengganu, Malaysia.
One such visualization of this effect may be approximated by these hypothetical population pyramids.
