Let me try that again......
Low birth weight infants are not counted against the “live birth” statistics for many countries reporting low infant mortality rates.
According to the way statistics are calculated in Canada, Germany, and Austria, a premature baby weighing <500g is not considered a living child.
But in the U.S., such very low birth weight babies are considered live births. The mortality rate of such babies - considered “unsalvageable” outside of the U.S. and therefore never alive - is extraordinarily high; up to 869 per 1,000 in the first month of life alone. This skews U.S. infant mortality statistics.

Some of the countries reporting infant mortality rates lower than the U.S. classify babies as “stillborn” if they survive less than 24 hours whether or not such babies breathe, move, or have a beating heart at birth.
Forty percent of all infant deaths occur in the first 24 hours of life.
In the United States, all infants who show signs of life at birth (take a breath, move voluntarily, have a heartbeat) are considered alive.
If a child in Hong Kong or Japan is born alive but dies within the first 24 hours of birth, he or she is reported as a “miscarriage” and does not affect the country’s reported infant mortality rates.

Too short to count?
In Switzerland and other parts of Europe, a baby born who is less than 30 centimeters long is not counted as a live birth. Therefore, unlike in the U.S., such high-risk infants cannot affect Swiss infant mortality rates.
Efforts to salvage these tiny babies reflect this classification. Since 2000, 42 of the world’s 52 surviving babies weighing less than 400g (0.9 lbs.) were born in the United States.
Thanks. I was actually somewhat aware of the complexities of comparing statistics from one nation to another. Similar problems pop up with comparing crime rates and other factors.
Statistics compiled with wildly different criteria can’t really be compared very profitably.
As I pointed out, life expectancy is usually calculated at birth, which makes infant mortality, however calculated, wildly influential.
I have seen life expectancy tables at age 20 and 50, and those seem to be more likely to be comparable.
