The US life expectancy is lower because of unnatural deaths, we're crazy like that.
I'm not joking either, look it up.
The infant mortality rate is BS too, there are a few things that contribute to poor rankings of the US:
- Many countries like France who I believe is top of the list have a cutoff for weight where the baby even if born alive and then dies is not recorded as death after birth. Every live birth in the US is considered live.
- Superior health care in the US that allows severely premature infants to be born alive that would never be born alive in another countries. These births are more likely to result in death.
- The black population which is considerably higher in the US has an abnormal amount of deaths in infants and this stat transcends all levels of income.
While on the topic the WHO's overall ranking for health is BS as well. As one example they based 25% of the score on how much was spent regardless of outcome, in other words a poor country like Cuba that spent nothing and outscores the US simply because they spent less... makes a lot of sense right?
I'll add one more reason to infant mortality list, the parade of low lifes unwilling to take the help available to them who's first visit to the doctor is when they are about to give birth. No neonatal care, poor lifestyle to begin with resulting in sick kids who end up dieing because of poor care in the home even if they are born alive and fairly healthy.
