Comparing the fertility behaviour of women from the different population groups allows to observe differences and similarities. This is less an indicator of integration than of assimilation, the measure of which shows the demographic context and the different challenges that the population groups are confronted with in organising their family life. For example, in the political and social climate of Switzerland today, a woman with many children will probably encounter more obstacles in training and education and in building up a career.
In 2020, the total fertility rate of Swiss and foreign national mothers born in Switzerland were very similar (1.36 and 1.45). The differences were greater for women born abroad and the indices were higher: Swiss women have a TFR of 1.43 and foreign nationals 1.81.
