As of August 2012, an estimated 369,000 people (or about 94,000 households) remain in 541 IDP sites across the earthquake affected areas in Haiti. This reflects a 5% decrease in overall (individuals) population compared to last period (June 2012). The rate of decrease remains steady as compared to last period where a decrease of 7% was observed. This suggests that the effects of Tropical S ISAAC did not substantially change the total population in IDP sites. At least 19 of the 37 IDP sites (51%) that closed between June to August 2012 have closed through the support of return programs by various actors.
