Stanley, that Telegraph story is full of interesting details:
More than one in five births in Britain last year was to a woman from overseas, the first official analysis of the impact of immigration on fertility showed yesterday…
The Pakistani rate of 4.7 children per mother is almost three times the British-born rate of 1.7.
To be sure, the Pakistani UK population is much smaller than the native population. But, when couple A has eleven grandkids and couple B has one-point-four grandkids, you’d be surprised how quickly that evens things up.
As for the argument that Pakistani fertility rates decrease over time, well, in 1991 the TFR was 4.8, and in 2001 it was 4.7, and currently it’s 4.7. True, immigrant groups traditionally align their fertility rate with the broader population within a couple of generations. But these communities are resisting that pattern to the point where, beginning in the Eighties, the Pakistani TFR in England & Wales actually increased. According to the Council of Europe (warning: 600 page PDF), Bangladeshis in the United Kingdom have higher fertility levels than Bangladeshis in Bangladesh – just as, in Norway, Somali, Moroccan and Turkish immigrant communities have higher fertility levels than those of their countries of origin.
The above are facts. What they mean is a matter of opinion. But what’s happening in Europe is one of the biggest real-estate transfers in history.
