Population aging is defined as the increase in the proportion of the elderly population within a given population. But isn't it a plural concept in its causes, variations and geography?
Measuring ageing involves considering the ratio between the number of elderly people and the total population. Concerning the numerator, since the Second World War, France has recorded, with the exception of the years when the small generations born during the First World War reached the age of 65, an increase in the number of elderly people, a phenomenon for which the neologism "gerontogrowth" has been proposed [1] .
The two causes of gerontogrowth spain phone number list leading to aging “from above”
This gerontogrowth has two causes. The first is that the life expectancy of the elderly has increased over the years, consequently improving their survival rate and therefore their numbers. In France, despite small annual variations in the increase in the life expectancy of the elderly, in particular according to the deadly intensity of seasonal flu, the trend has been increasing with the exception of 2003, under the effect of a heatwave that caused around 15,000 additional deaths, then the years 2020, 2021 and 2022, under the effect of excess mortality due to the Covid-19 pandemic. Thus, life expectancy at 65, which for women was 14.3 years in 1946, then 16.8 years in 1970, will be 23.6 years in 2024. For men, the data, admittedly less favourable, particularly due to overconsumption of alcohol, tobacco or drugs, are respectively 12.2 years, 13 years and 19.8 years.
