In the early 1950s, the immigration wave subsided, and emigration increased; ultimately, some 10% of the immigrants would leave Israel for other countries in the following years. In 1953, immigration to Israel averaged 1,200 a month, while emigration averaged 700 a month. The end of the period of mass immigration gave Israel a critical opportunity to more rapidly absorb the immigrants still living in transit camps. The Israeli government built 260 new settlements and 78,000 housing units to accommodate the immigrants, and by the mid-1950s, almost all were in permanent housing. The last "ma'abarot" closed in 1963.
