How many Jewish refugees were there? 870,000 (not including refugees from Iran). [Palestinian refugees: estimates vary between 400,000 and 700,000.]
How much did the Jews lose? No official figures exist. The property and belongings of the Jewish refugees, confiscated by the Arab governments, has been conservatively estimated at about $2.5 billion in 1948 dollars. Invest that money at a modest 6.5% over 57 years and you have today a sum of $80 billion.
In an interview in June 2007, 'Righting a historical injustice', Dr Heskel Haddad of WOJAC estimated that the value of Jewish property seized at today's prices is between $200 and 300 billion. In an article dated 13 February 2003, Itamar Levin of Globes Online estimated the value of Jewish property lost at $30 billion, with that seized in Iraq, Syria and Egypt alone at between $8 - $10 billion.

Some claim that Jewish property lost in Iraq alone amounts to $20 billion.
Palestinians: in the early 1950s, the UN Conciliation Commission for Palestine estimated the value of lost Palestinian property at £122 million, or approximately $1.85 billion 1990 US dollars. This was the only independent study ever done of Palestinian losses. In 1999, the Palestinians presented a $670 billion compensations claim before the European Union Commission for lost assets, use of those assets and emotional distress (p.223 Locked doors by Itamar Levin).
Jewish-owned land lost in Arab countries:38,625 sq miles
[By way of comparison, Israel's total land area is 7,992 square miles.] WOJAC has also estimated deeded property lost in Arab lands to cover 100,000 sq.km. According to a UN report of 20 November 1951, Palestinian land lost amounted to 6,3027 sq.miles (16,324 sq km), of which 1,766 sq. miles were cultivable.]
