Congressional Research Service Reports for the People

It is estimated that in total (including those displaced prior to the war) there may be as many as 2 million Iraqi refugees who have fled to Jordan, Syria, and other neighboring states, and approximately 2.7 million Iraqis who have been displaced within Iraq itself. Between 2004-2007, the violence and insecurity resulting from the ongoing sectarian strife, terrorism, and insurgency in Iraq produced substantial civilian displacement in different parts of the country.
