In 2000 Germany had a sort of distorted, bulging human population graph which is due to the massive reproduction after World War II. That new large population produced another which is the there are those two bulges. Another reason why it is distorted like that is because of the new modern medicine which stops people from dying at these ages, as well as better hospitals for giving birth.

The first German graph does not differ much from the second one, except there is only one lump instead of two. This is because the massive reproduction era after the was so long ago that most of those people died and now only the second wave remains. There are less young people, probably because people are educated about STDs’ and make more thoughtful decisions.
