And in France it's 82.7 years, the wealth of the US doesn't directly translate to good life expectancy, especially when you've got so many inequalities. The highest life expectancy is at 85 years in Japan. The average life exepctancy in the world in 72.6 years, 79 in Europe, 82.5 in Western Europe. With all due respect to Tunisia, it's better than average but still lower than "any western country".
Countries also count deaths differently. Some will count a premature baby at 26 weeks that dies as a death (the US), while others just say “it was never viable” so not a death.
Don’t need to average very many “zeros” to bring down an average.
That sounds wrong. There’s a whole range of life expectancy metrics that are calculated carefully as they constitute a fundamental metric about a population in everything from the insurance industry to the health industry. Life expectancy metrics are heavily used for geographic and historic comparison as they have standard and specific definition. The starting age is always specified - e.g. life expectancy at 18 or 60 or whatever. When the age is not specified, the implied age is zero or “life expectancy at birth”. I’ve never heard of “life expectancy at conception” nor can think that one country would calculate it but use the value for “life expectancy at birth”.
There is huge variability in how deaths are reported for newborns.
“Many countries, however, including certain European states (e.g. France) and Japan, only count as live births cases where an infant breathes at birth, which makes their reported IMR numbers somewhat lower and increases their rates of perinatal mortality.[111] In the Czech Republic and Bulgaria, for instance, requirements for live birth are even higher.”
Read the “Methods of estimation” section where the standardization process is described. This would be a lot simpler is you could simply provide a reference to support the claim that the life expectancy at birth metric in the USA is calculated differently to that in other countries. Your claim seems to based on differences in calculation a different metric, infant mortality rate.
