 On 31 May 2011 , an unreleased draft report based on a survey commissioned by the US Agency for International Development ( USAID ) challenged the Haiti earthquake death toll and several damage estimates . The unpublished report put the death toll between 46 @,@ 000 and 85 @,@ 000 and put the number of displaced persons at 895 @,@ 000 , of which only 375 @,@ 000 remained in temporary shelters . The unreleased report , which compiled its figures from a door @-@ to @-@ door survey , was done by a Washington consulting firm , <unk> <unk> . A US State Department spokesperson said the report had inconsistencies and would not be released until they were resolved . As of January 2012 , USAID has not released the report and states at its website that 1 @.@ 5 million people were displaced , of which 550 @,@ 000 remain without permanent shelter . The most reliable academic estimate of the number of earthquake casualties in Haiti ( over 95 % were in the immediate Port @-@ au @-@ Prince area ) " within six weeks of the earthquake " appears to be the 160 @,@ 000 estimate in a 2010 University of Michigan study .
