In Warsaw, the Jews, comprising 30% of the city overall population, were forced to live in 2.4% of the city's area, a density of 7.2 people per room.[2] In the ghetto of Odrzywół, 700 people lived in an area previously occupied by five families, between 12 and 30 to each room. The Jews were not allowed out of the ghetto, so they had to rely on smuggling and the starvation rations supplied by the Nazis: in Warsaw this was 253 calories (1,060 kJ) per Jew, compared to 669 calories (2,800 kJ) per Pole and 2,613 calories (10,940 kJ) per German.
