A man walks in front of shops in Nairobi's Kibera district stretched  over six hundred acres of mud and filth,November 28, 2003. According to  a UN report the Kibera district was classed as the largest slum in the  world where over 600,000 people are living illegally as squatters in  squalid, unhealthy tin-roofed mud huts, mostly without water,  sanitation, public services and frequent outbreaks of violence. This  year's report entitled "The Challenge of Slums", is packed with  statistics and figures on our rapidly urbanizing world, in which the  total number of people currently living in slums is estimated at 928  million.
