Not sure if KL Ravensbrück inmate number allocations are available online already but here is an overview of the inmate number blocks 1939-41 and when they were allocated (the notes have Polish prisoner counts as that is my personal interest). Hopefully it might be of interest to collectors of camp correspondence
KL Ravensbrück was set up at the beginning of 1939 and up until 31st August 1939 the camp records list 2096 female prisoners.
Until 1942, KL Ravensbrück was the only female prisoners' camp under the authority of the Inspector of Concentration Camps in Reichsfiihrer SS and the Chief of the German Police Office.
During the period 01/09/1939 to 31/12/1939 a further 487 prisoners were registered in the camp with ID numbers 2097 - 2583. The group included 10 Poles.
During the period 01/01/1940 to 31/12/1940 a further 2755 prisoners were registered in the camp with ID numbers 2584 - 5338. The group included 1000 Poles.
During the period 01/01/1941 to 31/12/1941 a further 3633 prisoners were registered in the camp with ID numbers 5339 - 8971. The group included approx. 1300 Poles.
In the years 1939-1941, the prisoners of the camp were mostly Gypsies (Roma), Germans, Poles and Jews, other nationalities were still in the minority.
Because the majority of the Ravensbrück documentation was destroyed by the Nazis shortly before the end of the war it is impossible to establish the circumstances of death amongst the prisoners or even the death rate in given time periods of the camp's existence.
