Translated from BT (2003)
“Disabled immigrant children cost Danish municipalities millions.
In Copenhagen municipality alone, the number of disabled children increased 100 percent in 10 years.
The explanations are many: Many women give birth later in life. More disabled children survive. But it also turns out that immigrants have more disabled children than Danes do.
A large part of the reason is due to the many cousin-marriages among immigrants. This doubles the risk of having a disabled. …
Already in 2000 it turned out that while 13 percent of all children were immigrants in Copenhagen Municipality, they accounted for 24 percent of severely disabled children. …
Merete Lefelt contacted 330 families with disabled children in Copenhagen. She estimates that one third of their clients have a foreign cultural background. …
One reason for the significant increase is believed to be the cousin marriages among many Muslims.”
