Men find it harder to move out of their homes than women do: At the age of 23, nearly half (48.4 percent) of the sons still live with their parents.
Daughters, on the other hand, have already left their parents' home at the age of 22 in more than half of the cases. At the age of 23 only 36 percent of them live at home. This is reported by the Federal Statistical Office, citing the Microcensus 2017 (pdf).
At the age of 25, more than a third (34 percent) of men live at home, in their early thirties it is just over every ninth, at the age of 40 only under four percent.
At the age of 25, however, only 21 percent of women live in their parents' home, with only 30 being only 17 percent.
Numbers in men are declining
However, there is something moving among men - towards more autonomy: Since the mid-1990s, the proportion of 25-year-olds still living in their parents' home is declining, while that of young women has remained roughly the same.
If you look only at students, the trend is the other way round. According to a study by the Center for Higher Education Development (CHE), more and more students live with their parents. This could be related to the high rents in the popular university towns and the declining average age of students.
