The population distribution in Tanzania is extremely uneven. Most people live on the northern border or the eastern coast, with much of the remainder of the country being sparsely populated. Density varies from in the Katavi Region to in Dar es Salaam. Approximately 70 percent of the population is rural, although this percentage has been declining since at least 1967. Dar es Salaam is the "de facto" capital and largest city. Dodoma, located in the centre of Tanzania, is the "de jure" capital, although action to move government buildings to Dodoma has stalled.
