UPDATE: And as we see from this paper from the WHO, live birth in the US is not what it means in France, for example. In the US it's any sign of life, in France and Belgium it's living for some period of time: "it has also been common practice in several countries (e.g. Belgium, France, Spain) to register as live births only those infants who survived for a specified period beyond birth"
For instance, some countries (like France) ignore births before x weeks whereas most countries (including the U.S.) include all births.
Beyond that, the U.S. leads the world in premature birth survival despite also leading the world in assisting people with fertility problems to become pregnant and add to the statistics that on the surface seem problematic for the U.S.
France: 3.34 US: 5.90 (Per 1000 live births)
