In France, ethnic statistics are banned by law. So how do we know? The medical services conduct screening for genetic diseases, including sickle-cell disease, an evolutionary adaptation to malaria that is common among non-Europeans. So people of non-European ancestral origin are considered at greater risk of developing this disease and are therefore targeted for screening. This is where the figure comes from.
So this graphic is telling us that 37.2% of newborns are African/Asian. In the Greater Paris area, it is an astounding 69.06%.
