Tanzanians consider the Datoga a backward people. They resist formal education and only about 5% of the Datoga speak Swahili, the national language of Tanzania. Their literacy rate is only 1%. Their hygienic standards are low and they have high infant mortality rate. The Datoga bypassed modern political developments. They live within a small circle of contacts with neighboring people with whom they mostly have a conflictual relationship. These factors contribute to their isolation within Tanzania.
