UK immigrants' birthrate falls to lowest on record, converging with local women's rate.

Without immigrants from poorer lands, many European countries would have seen their population falling for decades now. Immigration is what makes the UK, France, Germany... different from Japan, where a very ethnically homogeneous population is shrinking by around 200,000 heads a year.

Even the Queen's family was from Germany

Yet, foreign-born citizens are also not the magic fix. After a while, they, or more likely their children, will become locals, with local reproductive pattern. 

From the Telegraph: "No sex please we're British now"

...
"It could be a case of “no sex please we’re British now”- births to foreign-born mothers have fallen for the first time in a decade suggesting an end to the UK’s migrant baby boom.

New official figures also show that the fertility rate among foreign-born women in England and Wales fell to its lowest level on record last year.

But after a decade of mass migration the proportion of newborn babies with a mother originally from overseas also reached its highest level, the figures from the Office for National Statistics show."

...

"The Total Fertility Rate – which estimates how many children a typical woman would have in their lifetime if they replicated current patterns – fell to 2.19 children per woman among immigrants, down from 2.29 a year earlier.

It was the lowest rate since annual records began in 2004 and the ONS said it was also below rates indicated in the 2001 and 1991 censuses.

While immigrants have traditionally had more children than people born in the UK, the drop suggests that birth rates among immigrants are converging with those seen in British families."

"The ONS explained in a commentary that the falling fertility rates among migrant women represents a “change in trend” and said that falling fertility was effectively outweighing the effects of continued immigration in birth figures.

The figures also suggest that the rate could fall further the longer immigrants remain in the UK."

What will happen when the poor countries become rich, with rich world's fertility rate? And few have to migrate for economic reasons? Already, Iran's birthrate is now lower then the UK's (see part 2/7)
