Kidding aside, if muslim birthrates exceed native rates by say 2 to 1 (I think natives are at about 1.5 kids per female, with muslims over 3.0), then your 30:1 ratio will be cut in half in a couple of generations, even without immigration.

I think it's rather more complex than that. Immigrant birthrates tend to be higher in any Western country, but this difference shrinks as the new generation takes on Western ways.

Immigration to the UK is more strictly controlled than it was 20 years ago and as I said before, our main source of immigrants is now from Eastern European countries that have recently joined the EU. The strength of our economy and low unemployment rate is what attracts them here. We're expecting even more when Romania and Bulgaria join the EU in January!
