“Finally, are infants counted in that life expectancy number? In European countries, premature births are not counted as viable lives, so they are not counted towards infant mortality. Not so in the U.S. How does this factor (if at all) into life expectancy?”

Here’s one, but google is your friend:

Lots of info on this on the web. Find out how they /sometimes/ don’t count preemies in the UK until they are at a facility certified to care for preemies. If it shows up dead to that facility, it wasn’t a live birth even if it was born alive at another hospital.
