Influences on the average age

Various factors have an influence on the age of a country's population. In economic nations and highly developed countries in particular, reliably good nutrition and medical care leads to higher life expectancy and thus to an increase in the age of the population. A higher proportion of women also results in a slight increase, as women generally have a higher life expectancy.

Average age However, the birth rate has the greatest influence. In almost all countries with higher income the birth rate is remarkably low (cf. Population growth by country) and in poorer countries very high.

In most industrialised countries, for example, the lack of young people is currently causing the average age to rise, while in less developed countries the age is stagnating or even falling.
