That is an almost impossible question to answer.\n\nYou are not asking about the attack, but during the entire war.  And both cities were under attack from 1943 on.\n\nHiroshima was a major source of industry, making both aircraft and other munitions for the Japanese War industry.  Nagasaki was one of the major ports of Japan, and had one of the largest Naval Bases in the city.  So both had been subjected to bombardment for over a year before the war ended.\n\nA better question might be "How many would have died if they were not bombed?"
how many people died in Hiroshima and Nagasaki durring WWII?
