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, reliable 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 incomes, the birth rate is remarkably low (cf. Population growth by country) and very high in poorer countries.

In most industrialized 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.

* Dependent territories

The following countries are not sovereign states, but dependent territories or areas of other states:

Hong Kong: Special administrative region of China
Isle of Man: autonomous crown dependency of the British Crown
Puerto Rico: unincorporated territory of the US

Data sources

Median age is published every five years by the United Nations Department of Economic and Social Affairs. The former CIA Factbook also listed a number of these data. Life expectancy is based on data from the Population and Vital Statistics Report of the United Nations. All data are projections or estimates based on available population figures.
