Casualties of the 2010 Haiti earthquake
Casualties of the 2010 Haiti earthquake include both civilian and government officials, locals and foreigners – however the overwhelming majority of those killed and wounded in the quake were Haitian civilians. A number of public figures died in the earthquake, including government officials, clergy members, musicians, together with foreign civilian and military personnel working with the United Nations. On 15 January, the Red Cross estimated the death toll at between 45,000 and 50,000, however by 24 January, Communications Minister Marie-Laurence Jocelyn Lassegue said the death toll was over 150,000 in the Port-au-Prince metropolitan area alone. Haitian president René Préval reported on 27 January that ""nearly 170,000"" bodies had been counted.On 21 February, Preval raised that estimate to 300,000. In February, prime minister Jean-Max Bellerive estimated that 300,000 had been injured. Speaking in Miami in June 2010, Bellerive also estimated the number of deaths had been 300,000. On the first anniversary of the quake, Bellerive raised the death toll to 316,000. He said that was, in part, because of the recovery of additional bodies. A University of Michigan study in 2010 estimated about 160,000 deaths.
