Effective monitoring of IDP's in Abidjan has been hampered by their invisibility. UNFPA and UNCHR carried out surveys in 2005 and 2007 respectively; however, these did not cover all of Abidjan and were not representative. We made Abidjan a case study to address the need for information about idps and because the city met our study’s criteria. Initial planning for the survey began in March 2007, and the survey was conducted in June 2007.
