An influx of Holocaust survivors and Jews from Arab and Muslim countries to Israel during the first three years increased the number of Jews from 700,000 to 1,400,000. By 1958, the population of Israel rose to two million. Between 1948 and 1970, approximately 1,150,000 Jewish refugees relocated to Israel. Some new immigrants arrived as refugees with no possessions and were housed in temporary camps known as ''ma'abarot''; by 1952, over 200,000 people were living in these tent cities. Jews of European background were often treated more favorably than Jews from Middle Eastern and North African countries—housing units reserved for the latter were often re-designated for the former, with the result that Jews newly arrived from Arab lands generally ended up staying in transit camps for longer. During this period, food, clothes and furniture had to be rationed in what became known as the austerity period. The need to solve the crisis led Ben-Gurion to sign a reparations agreement with West Germany that triggered mass protests by Jews angered at the idea that Israel could accept monetary compensation for the Holocaust.
