1. Population by age 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.

Not long ago, in 2014, the largest proportion of the world's population corresponded to people aged 25 to 54 (40.78%), followed by children aged 0 to 14 (25.79%). The 15-24 years old group corresponded to 16.61%. The groups of 55 to 64 years and over 65 years had just over 8% each.

While in Europe, the group of 0 to 14 years corresponds to 15.6%, in Africa it is 41.7%. In other words, while Europe has a few child population, Africa in a proportion almost reaches the middle. While Europe can be considered as a continent of old, Africa it has them in a very low percentage . The other continents have percentages that go from 6 to 10%.
