By 2010 sub-Saharan Africa will be home to an estimated 50 million orphaned children, and more than a third will have lost one or both parents to AIDS, according to a biennial report on global orphaning released this week by USAID, UNAIDS and UNICEF. The report, entitled 'Children on the Brink 2004' presents the latest statistics on historical, current and projected numbers of children under the age of 18 who have been orphaned by AIDS and other causes. In just two years, between 2001-2003, the global number of children orphaned due to AIDS has risen from 11.5 million to 15 million - the vast majority of which are in Africa.
