Cette statistique montre l'espérance de vie à la naissance aux États-Unis de 2007 à 2022. En 2022, l'espérance de vie moyenne à la naissance de la population américaine était d'un peu plus de 77 ans. L'espérance de vie a augmenté après plusieurs années de baisse qui pourrait être liée à la crise des opioïdes et à l'utilisation d'armes à feu. L'espérance de vie à la naissance est un des indicateurs statistiques les plus utilisés pour évaluer le niveau de développement et l'indice de développement humain d'un État ou d'une région du monde.

Graph and download economic data for Life Expectancy at Birth, Total for the United States (SPDYNLE00INUSA) from 1960 to 2023 about life expectancy, life, birth, and USA.

This statistic shows the average life expectancy in North America for those born in 2022, by gender and region. In Canada, the average life expectancy was 80 years for males and 84 years for females.

Life expectancy in North America

Of those considered in this statistic, the life expectancy of female Canadian infants born in 2021 was the longest, at 84 years. Female infants born in America that year had a similarly high life expectancy of 81 years. Male infants, meanwhile, had lower life expectancies of 80 years (Canada) and 76 years (USA).

Compare this to the worldwide life expectancy for babies born in 2021: 75 years for women and 71 years for men. Of continents worldwide, North America ranks equal first in terms of life expectancy of (77 years for men and 81 years for women). Life expectancy is lowest in Africa at just 63 years and 66 years for males and females respectively. Japan is the country with the highest life expectancy worldwide for babies born in 2020.

Life expectancy is calculated according to current mortality rates of the population in question. Global variations in life expectancy are caused by differences in medical care, public health and diet, and reflect global inequalities in economic circumstances. Africa’s low life expectancy, for example, can be attributed in part to the AIDS epidemic. In 2019, around 72,000 people died of AIDS in South Africa, the largest amount worldwide. Nigeria, Tanzania and India were also high on the list of countries ranked by AIDS deaths that year. Likewise, Africa has by far the highest rate of mortality by communicable disease (i.e. AIDS, neglected tropics diseases, malaria and tuberculosis).

Cette statistique présente l'espérance de vie moyenne à la naissance dans le monde en 2021, par continent et région ainsi que par sexe. L'Australie et la Nouvelle-Zélande présentent l'espérance de vie la plus élevée en 2021, avec une durée de vie moyenne prévue de 85 ans pour les femmes et 82 ans pour les hommes, pour les personnes nées en 2021. L'Europe et l'Amérique du Nord ont une espérance de vie qui avoisinne également les 80 ans. Inversement, c'est en Afrique sub-saharienne que l'espérance de vie est la plus faible : 61 ans pour les femmes et 57 ans pour les hommes. Sur tous les continents, l'espérance de vie est plus élevée pour les femmes que pour les hommes.

L'espérance de vie est une mesure statistique qui évalue la durée de vie d'une personne, sur la base de facteurs démographiques tels que le sexe, l'âge actuel et l'année de naissance. La mesure la plus fréquemment utilisée est l’espérance de vie à la naissance ou à l'âge zéro.

From the mid-19th century until today, life expectancy at birth in the United States has roughly doubled, from 39.4 years in 1850 to 79.6 years in 2025. It is estimated that life expectancy in the U.S. began its upward trajectory in the 1880s, largely driven by the decline in infant and child mortality through factors such as vaccination programs, antibiotics, and other healthcare advancements. Improved food security and access to clean water, as well as general increases in living standards (such as better housing, education, and increased safety) also contributed to a rise in life expectancy across all age brackets. There were notable dips in life expectancy; with an eight year drop during the American Civil War in the 1860s, a seven year drop during the Spanish Flu empidemic in 1918, and a 2.5 year drop during the Covid-19 pandemic. There were also notable plateaus (and minor decreases) not due to major historical events, such as that of the 2010s, which has been attributed to a combination of factors such as unhealthy lifestyles, poor access to healthcare, poverty, and increased suicide rates, among others. However, despite the rate of progress slowing since the 1950s, most decades do see a general increase in the long term, and current UN projections predict that life expectancy at birth in the U.S. will increase by another nine years before the end of the century.
