What would be the level of fertility in France if there were no immigrants?

In France, one birth in 8 is to an immigrant mother, while only one inhabitant in 14 is an immigrant, i.e. a foreign national born outside France and who has been living in France for over a year. Immigrants contribute more to the birth rate than native French people because they are more often of childbearing age and because their fertility is slightly higher than the rest of the population – half a child more per woman on average. This fertility difference has little impact on the national average. Fertility in France was 1.92 children per woman in 2005, and without immigrants it would have been 1.82.
