I take your point but that doesn't explain the other national / racial groups that would be expected to appear in the care system that don't seem to turn up.Take into account ‘Izzat’ (family honour) which would (generally) preclude an Asian child being taken into care, instead, they are farmed out to aunts and uncles. This way, they remain a community asset...
Re: your previous on ‘looked after’ Asian kids, the only one I’m familiar with was in the predicament because both his parents were in jail. For child trafficking and slavery offences.
Personally, I think most of this thread is a case of violent agreement and nitpicking over details.
