Why would you need data on other communities. The case is about the increase in birth defects.
I need data about other communities to form an opinion because the article says (my emphasis):
"When inbreeding persists through generations (when cousins get married who are themselves the children of cousins), the risks are far higher, which is why
British Pakistanis account for 3.4 per cent of births nationwide but 30 per cent of recessive gene disorders, consanguineous relationships are the cause of one in five child deaths in Redbridge and the NHS hires staff specifically to deal with these afflictions."
So I want to know what the percentage of recessive gene disorders are in other communities when cousins get married who are themselves the children of cousins. Given this is quite a widespread practice in Hindu communities, they might object to a ban. Maybe the Hindus are better at analysing their family history or having genetic tests done before they go through with a cousin marriage so as a result there are less recessive gene disorders in their community.
