I was reading "Nazi Gender Policies" by Gisela Bock, in "History of women in the West", and in it she mentions that early on there was some increase in German Women's birthrate, but that it could be attributed mostly to economic recovery, but there wasn't really an extensive review of how State policy affected birthrates, if at all, leaving me a little unclear with the consequences of Nazi Gender policy. So my questions are what were, throughout the years of Nazi rule, the full effects on birthrates and demographics in general of the pronatalist Nazi policies? Was there a significant difference in periods, for example did women in late war years tended to have more or less children that previously? And which of the effects could be attributed to which policy? Also, has sterilization policy negated any of the positive effects on birthrates? Has the number of those deemed "unfit" by the Nazis did decrease in a way that made the "race" more "healthy"?
I actually wrote a paper on women in Nazi Germany and this is a very late answer but I hope it will help you some, if you're still curious. This is definitely a very general overview.
Yes, the population of Germany did grow under the Nazi regime. It was recognized that a large population would be crucial in order to carry on the beliefs of the Nazi party long after Hitler/other leaders had passed away. And of course, the role of child-bearing fell to the women.
What's important to note is that the Nazi Party had a very "traditional" view of women, which was a stark contrast to the changing views of women going on in the rest of the world. Nazi women were expected to be home makers and child bearers and even though young girls were allowed to go to school, they were taught about marriage and how to tend to the house.
Women accepted this role in society because it was absolutely glorified. There was so much propaganda about motherhood in Nazi culture and there were also programs in place to encourage couples to have children. A couple of them are...
The Law of Encouragement of Marriage (1933): This law was passed pretty soon after Hitler rose to power. This law gave newly married couples a government loan of 1000 marks which is about 9 months of salary for them. This loan was expected to be paid back UNLESS the couple had children. If they one kid, 25% of the loan was forgiven. If they had two kids, 50% of the loan was forgiven. If they had 3 kids, 75% of the loan was forgiven. If the couple had 4 or more kids, their loan would be completely forgiven. So, if they went on to have kids, they would get free money! About 800,000 couples took up this offer.
Mother's Day: This was a holiday established by Hitler on his mother's birthday in her honor. This was more of a public glorification event. On this day, women were awarded the Mother's Cross Award, which had 3 different levels. Women with 4 or more children got a bronze cross, women with 6 or more children got a silver cross, and the women who had 8 or more children got a gold cross. Those who got the gold cross received the award from Hitler himself and they also got extra rations.
So, the glorification of motherhood helped to increase population growth.
