The 2011 Census outcomes showed the complexities of the challenges facing the country. The population size has increased by 16 per cent from 2001 to 2011. There are marked differences in population growth across provinces and regions. Furthermore, the number of households without access to basic services remains high at just over 4 million. National Treasury stated that interventions contained in the 2013 Division of Revenue Bill that sought to improve the delivery of basic services and infrastructure include the introduction of the new local government equitable share formula that promotes accountability and measures to improve the effectiveness of infrastructure planning.
