The
dala dala developed as an illegal taxi in
Dar es Salaam, the largest city in Tanzania, due to a deteriorating system of government-run public transport in an environment of rising demand for such services. Between 1975 and 1983, the year
dala dala were legalized, the number of buses operating in
Dar es Salaam declined by 36% while the population increased by around 80%. In 1983, the government transport company was allowed to subcontract to private entities, but due to high tariffs, this did little to substantially increase the number of licensed
dala dala. Further reforms in the late 1990s caused the number of legal minibuses to swell, and between 1991 and 1998 their numbers rose by 450%. Large amounts of pirate minibuses continued to exist, however, and in 1998 it was estimated that these comprised nearly half of all
dala dala in operation. By 1998
dala dala had almost completely superseded government-run public transport; in that year, a total of 12 government-operated buses plied the streets. Around that time there were somewhere between 7,650 and 6,300
dala dala in operation. ==Conductor==
