Warsaw ghetto contained 445,000 people

In early 1941, the Warsaw ghetto contained 445,000 people, including 130,000 from elsewhere, while the second-largest, the Łódź ghetto, held 160,000. Although the Warsaw ghetto contained 30 percent of the city's population, it occupied only 2.5 percent of its area, averaging over nine people per room. The massive overcrowding, poor hygiene facilities, and lack of food killed thousands. Over 43,000 residents died in 1941.
