After Nelson Mandela was elected in 1994 his government abolished racially segregated local authorities, creating ostensibly integrated municipalities. Today these range in size from Johannesburg, the commercial capital, to units like Mpofana that comprise a small town and rural areas. All are supposed to fund themselves through property taxes, business rates and charges for water, electricity and waste collection. The poorest also get a grant from the central government to fill any gap between revenue and expenditure.
