Dar es Salaam is Tanzania's most important city for both business and government. The city contains high concentrations of trade and other services and manufacturing compared to other parts of the country, which has about 80 percent of its population in rural areas. Downtown includes small businesses, many of which are run by traders and proprietors whose families originated in the Middle East and the Indian subcontinent—areas of the world with which the settlements of the Tanzanian coast have had long-standing trading relations.
