The population of Alsace-Lorraine was 1,814,000 in 1905 (source: Encyclopedia Britannica). Now that figure won't be materially different from 1911, so lets apply it to that year.Byron Angel wrote:

If we adjust the 1911 figures for this, we get France at 39,601,000 and Germany 67,174,000. The revised ratio is 0.5895 which I think is materially different to the 0.634 quoted above. It is significantly less than that of the 0.622 value given for 1929.
Another factor in this not considered is that 1919 onwards there was a ''Frenchification'' policy applied in Alsace-Lorraine which included deportation of some ethnic German settlors who arrived there post 1871. It is probably unlikely that it would materially effect the 0.622 for 1929 but it certainly wouldn't be lower without this.
