Sao Tome and Principe age structure

- percentage of population between 15 and 64 years old
- percentage of population 65+

In absolute figures (estimate):

We prepared a simplified model of the population distribution pyramid which is broken down into 3 main age groups. The groups are the same as we used above: population under 15, between 15 and 64 and population which is over 65 year old.

65+
15-64
0-14
male female

Note: The pyramid provided is not corresponding to data given above because the age groups have different number of years.

As we can see the Sao Tome and Principe population pyramid has an expanding type. This type of pyramid is common for developing countries with high birth and death rates. Relatively short life expectancy, as well as low level of education and poor health care are also describe such kind of population age distribution model.
