What has happened with the US life expectancy suddenly? If it is the expectancy "at birth" then there is no Covid effect, isnt it?
I dont get why it drops.
Nevertheless, good job China. Lifting a country from absolute poverty, poorer than any African country during the 1980s, growing to a top global economy, having world-class infrastructure, developing its society, becoming cleaner and modern. This all deserves huge respect - instead of a racist anti-China war.. just because one is afraid that their system MAY work better and outcompete our system.
Life expectancy is calculated from the mortality statistics of the recent past: the share of newborns that made it to one year old, one-year olds that made it to two years, etc. etc. accumulated to get the probability of a newborn making it to age X and then dying, assuming conditions stay the same (which they never do).
"At birth" just specifies the starting age. You could also look at life expectancy at 5 to exclude infant mortality, or even life expectancy at 69, though that won't tell you about the future survival of any particular 69-year-olds any more than life expectancy at birth tells you about the future survival of babies born today.
So the drop in life expectancy in countries with many covid deaths is likely to be followed by a jump back up as the number of covid deaths decreases, while China might experience something similar depending on how the current trend of increasing case counts develops.
