ERsatzlage. Supply of manpower to German Army?

[5th Horseman]

Does anyont have "accurate" numbers on the supply of recruits or replacements to the German Army between August 1914 and November 1918.
I have data on the yearly class call up and round numbers extimates for several years.
I'd love to see something like the BEFs STATISTICS OF THE MILITARY EFFORT OF THE BRITISH EMPIRE.
But I'll take any info.

Thanks.

A sample of data from the MILITARY EFFORT...as an example.
