German Dynamic Population Pyramid
Includes files for both East and West Germany, and Total, all on the same scale 1mm = 5,000 people.
Germany taken from the UN population data portal.
East and West Germany taken from the Human Mortality Database.
I am not certain, but I believe that the short time series available is because Germany's borders changed considerably during WWII, and so a stable defined region of "Germany" is not available.
