When studying the volume of people in the world, an important fact is to establish how many of them are children, youth and adults, because it influences work life, education and health services.

The world population is not distributed same way on all continents, so that, the percentages that we have known should be complemented with the population distribution of each one of them.

While countries with younger populations should generate more people who join working life, countries with a higher proportion of older adults should increase social security, especially retirement pensions employment for

The different proportions of the groups of age, or age groups, can be explained largely by means of two important factors: the levels of birth and mortality of each continent. The African continent is the one with the highest level of birth (4.7 average children per mother) and at the same time the lowest life expectancy at birth (59.5 years)

The study of the world population is enriched if some cases that allow comparison are compared. The countries with the highest number average number of children per woman (over 6) found in Africa: Niger (7.6), Somalia (6.6), Mali (6.4), Chad (6.3), Angola (6.3), Republic Democratic Republic of the Congo (6.2) and Burundi (6.1).
