Life expectancy

Life expectancy for men and women

A male child born in the United States today will live to be 74.8 years old on average. This puts the male citizens of the US in 43rd place in this ranking. On average, US women are 5.4 years older, reaching an age of 80.2. The world average age of death is a few years lower at 69.6 years for men and 74.5 years for women. Within the European Union, these are 78.2 and 83.6 years respectively.

Birth rate and death rate are given in births/deaths per 1,000 inhabitants within one year. The table shows the official data from the year 2022. In some minor cases, no data for this year are known, so previously published data were used.

Development of life expectancy worldwide

In the years 1960 to 2022, life expectancy has increased perceptibly worldwide. Starting at 50.7 years, it increased for men by 18.9 years to 69.6 years. For women, life expectancy increased by 19.9 years from 54.6 up to an average of 74.5 years since 1960.

Differentiation by region

What is life expectancy?

Life expectancy indicates the expected age that is estimated for a human being at the time of birth. This number of years is determined mainly from the current mortality rates. However, since these data only take into account the past, additional estimates are included to determine the future age due to external influences. These can be environmental factors as well as developments in health care. The average life expectancy is therefore not a measured value, but a prognosis for the future.

As the life expentancy steadily increases in most countries, the currect average age of death is bit lower than the expected. Depending on the country, it is between two and five years lower.

Above all, life expectancy is a result of the living conditions of a person or a population group. Essential factors are medical care, balanced nutrition and drinking water supply. Regionally occurring diseases such as malaria also play a role in the country comparison. These factors are influenced significantly by political factors, which is why life expectancy often derives from a country's standard of living.

The difference between men and women

In the vast majority of countries, women are four to eight years older than men. According to many scientists, this is not a purely biological difference. Instead it is also attributed to different behaviors. According to this view, men are less careful about their bodies than women. In fact, smokers and alcohol consumers are more common among men. Also, physical stress with simultaneous aversions to medical treatment and health precautions are responsible for this. Indeed, there is also an additional genetic reason for women's longer lives.

Influence of the mortality rate of children

A significant impact on life expectancy is the mortality rate of children. Both in the Middle Ages, as well as in the developing countries today, the death rate of children at birth or in the first few years of life is disproportionately high. These factors are already included in the average life expectancy. If one subtracts the proportion of children already deceased after the first years of living, the "average" is maintained, but the life expectancy of the rest increases.

* Dependent territories

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

• Bermuda: self-governing territory of the UK
• Hong Kong: special administrative region of China
• Macao: special administrative region of China
