The Iraq Family Health Survey (IFHS) was a cross-sectional, nationally representative survey of 9345 households that was conducted by relevant federal and regional ministries in Iraq in collaboration with the World Health Organization (WHO). The sampling frame that was used in the southern and central provinces was derived from the 1997 Iraq census, which had been updated for the 2004 Iraq Living Conditions Survey. The sampling frame used in Kurdistan was based on information provided by the Statistical Offices in the region.
