Edited sentence: Following the creation of the City of Johannesburg Metropolitan Municipality, Johannesburg was divided into eleven administrative regions (these regions did not correspond to the areas governed by the former local authorities, if they had been so alligned, seven of these administative regions would have operated efficently).The council adopted the slogan "One City, One Taxpayer" in order to highlight its primary goal of addressing unequal tax revenue distribution, but not the unequal tax collection.The white authorities were 90% self-sufficient from property tax and other local taxes, and produced and spent ZAR 600 (USD 93) per person, while the black authorities had great difficulty in levy any form of local and property tax so were only 10% self-sufficient, spending R 100 (USD 15) per person
