Haar maintains that all reasonable estimates of deaths from expulsions lie between around 500,000 and 600,000, based on the information of Red Cross Search Service and German Federal Archives. Harr pointed out that some members of the Schieder commission and officials of the Statistisches Bundesamt involved in the study of the expulsions were involved in the Nazi plan to colonize Eastern Europe. Haar posits that figures have been inflated in Germany due to the Cold War and domestic German politics, and he maintains that the 2.225 million number relies on improper statistical methodology and incomplete data, particularly in regard to the expellees who arrived in East Germany. Haar questions the validity of population balances in general. He maintains that 27,000 German Jews who were Nazi victims are included in the West German figures. He rejects the statement by the German government that the figure of 500–600,000 deaths omitted those people who died of disease and hunger, and has stated that this is a "mistaken interpretation" of the data. He maintains that deaths due to disease, hunger and other conditions are already included in the lower numbers. According to Haar the numbers were set too high for decades, for postwar political reasons.Ingo Haar, "Ursprünge, Arten und Folgen des Konstrukts 'Bevölkerung' vor, im und nach dem 'Dritten Reich': Zur Geschichte der deutschen Bevölkerungswissensch".
