Adolescent parents are quite rare in Germany, especially compared to the number in the USA. On a statistical basis, only the ages of mothers feature in survey. Th us, when talking about adolescent parents, only the mother is statistically registered. To ascertain the exact number is not very easy since age criteria vary among different publications. Some take all mothers younger than 21 years into account, while others only calculate those younger than 18 or 20 years.
