30.57 women for 100000 persons (thus, for about 50000 females of every age) have a breast implant every year in Germany. 84.3 women for 100000 people have that kind of operation in the US during the same time. In Venezuela, it's 137.9 women per 100 000 inhabitants.
It's weird and it's a pity. I think a few may need that because of some illness or the like. Most don't.
