Many Arabs claim that 800,000 to 1,000,000 Palestinians became refugees in 1947-49. The last census was taken by the British in 1945. It found approximately 1.2 million permanent Arab residents in all of Palestine. A 1949 Government of Israel census counted 160,000 Arabs living in the country after the war. In 1947, a total of 809,100 Arabs lived in the same area.1 This meant no more than 650,000 Palestinian Arabs could have become refugees. A report by the UN Mediator on Palestine arrived at an even lower figure — 472,000, and calculated that only about 360,000 Arab refugees required aid.

That website is a piece of right-wing junk, but their figures are still higher then yours.
