Kibera is the largest urban slum in Africa. The 2009 Kenya Population and Housing Census reports Kibera’s population as 170,070, contrary to previous estimates of one or two million people. Other sources suggest the total Kibera population may be 500,000 to well over 1,000,000 depending on which slums are included in defining Kibera.
Most of Kibera slum residents live in extreme poverty, earning less than $1.00 per day. Unemployment rates are high. Persons living with HIV in the slum are many, as are AIDS cases. Cases of assault and rape are common. There are few schools, and most people cannot afford an education for their children. Clean water is scarce and therefore diseases caused by related poor hygiene are prevalent. A great majority of people living in the slum lack access to healthcare.
