Unbelievable. We seem to go through this outright lie every few months.
It is a simple concept. There are NO uniform reporting procedures, each Country is free to report what it wants based on what it determines is appropriate.
Example...
Live births. The US reports every birth that occurs that the infant is alive ON BIRTH. No matter the viability of keeping said infant alive. Other Countries do not. Some have a waiting period during which if the infant dies, it is NOT considered to have been a live birth. Each individual Country determines how it will determine what it reports and there are NO uniform procedures.
This means trying to compare countries across the world is a waste of time.
