The post you're replying to argues that Muslim immigration has raised fertility rates, and your numbers confirm that opinion. Even the falling Muslim fertility rates, after 15 years, that you mention are far above the "native" rates (2.9 as opposed to 1.7 in Holland, and you call the idea that Muslims raise fertility rates "horseshit"?!). The rates that you cite for Germany show a Muslim population that, even after 40 years, is growing at a rate of 20+% per generation, whereas the "native" population is declining.
To this decades-old immigration that is still growing strong, we must add recent immigrants, who are much more religious and have much higher fertility rates.
zeteo Muslim immigration into France accounts for the high fertility.
The second development to note is that INED, France's National Institute of Demographic Studies, has done some detailed research and concluded that France's immigrant population is responsible for only 5 percent of the rise in the birthrate and that France's population would be rising anyway even without the immigrant population.
France is an interesting and peculiar case, with lots of natalist policies and with laws impeding the collection of statistics based on religion and ethnic origin. I'd love to see the original INED study, though, if you have a link.
