The population living in unplanned peri-urban settlements has been decreasing as a proportion of total urban population, while the urban population has also been increasing. Therefore the numbers have been increasing while the proportion has gone down. Both impact on the extent of slum areas. About 70% of urban residents in most cities in Tanzania live in unplanned settlements, slums or squatter areas. A special programme to upgrade these unplanned urban settlements is being implemented in two phases: First is identification and registration; and second is upgrading infrastructure and utility services. In addition, plot surveying and allocation is being done, with about 55 000 plots surveyed and allocated since 2004 (Government of Tanzania 2000-2008).
