In 2003, the increase in life expectancy The increase may stalled (–0.1 years for women, +0.1 years for men) due to a short but very intense heatwave. Life expectancy then, each time, started to rise again once the cyclical episode had passed. than the past trend. This is due to a well-known phenomenon, called the “harvest effect” (Barbieri, Nizard and Toulemon, 2006): some fragile people die earlier due to unusual health or climatic conditions. These deaths reduce those that occur the following year, whatever the cause. The increase may We must therefore be careful not to overinterpret cyclical fluctuations in life expectancy and also take an interest in long-term developments, which are useful for example for population projections and prospects for the balance of pension systems.
The “harvest” effect can therefore
Lead to a temporarily stronger increase in nepal phone number library life expectancy than in the past, but a cyclical episode can also induce a more lasting “march” on life expectancy. This was the case following the heatwave of 2003: the increase in life expectancy resumed more sharply than expected in the absence of a heatwave; the attention paid to the elderly in the event of extreme heat was greater, with various measures taken, for example the implementation of a national heatwave plan triggered in the event of particularly high temperatures (InVS, 2006).
Life expectancy in a given year
Does not allow us to know the lifespan of a generation.
In a given generation, people will go through mortality this approach is particularly useful conditions for a period of about a hundred years. The marked decline in 2020 tells us that the pandemic had a particularly strong impact on mortality germany cell number conditions in 2020, and that the decline in life expectancy is of an unprecedented magnitude compared to the trends observed for more than fifty years. However, the 0.6-year decline in life expectancy at birth for men in 2020 does not mean that men born in 2020 lost 0.6 years of life compared to those born a year earlier.
