The 872 days of the siege caused unparalleled famine in the Leningrad region through disruption of utilities, water, energy and food supplies. This resulted in the deaths of up to 1,500,000 soldiers and civilians and the evacuation of 1,400,000 more, mainly women and children, many of whom died during evacuation due to starvation and bombardment.
Economic destruction and human losses in Leningrad on both sides exceeded those of the Battle of Stalingrad, the Battle of Moscow, or the atomic bombings of Hiroshima and Nagasaki.
The siege of Leningrad is the most lethal siege in world history, and some historians speak of the siege operations in terms of genocide, as a "racially motivated starvation policy" that became an integral part of the unprecedented German war of extermination against populations of the Soviet Union generally.
Civilians in the city suffered from extreme starvation, especially in the winter of 1941–42. From November 1941 to February 1942 the only food available to the citizen was 125 grams of bread, of which 50–60% consisted of sawdust and other inedible admixtures. For about two weeks at the beginning of January 1942, even this food was available only for workers and military personnel.
In conditions of extreme temperatures, down to −30 °C (−22 °F), and city transport being out of service, even a distance of a few kilometers to a food distributing kiosk created an insurmountable obstacle for many citizens. Deaths peaked in January–February 1942 at 100,000 per month, mostly from starvation. People often died on the streets, and citizens soon became accustomed to the sight of death.
