In Tanzania, as it is with other developing countries, the number of people with disabilities is substantive, although no up-to-date data is available. However, official data from the National Disability Survey of 2008 conducted by the National Bureau of Statistics (NBS) indicate that 3.2 million Tanzanians (7.8%) of the population aged seven years and above have some form of disability and up to 5.4 million (13.2%) are affected by disability.
