For example, many small towns, while classified as rural, display urban characteristics in terms of population density and service provision models. The speed with which many of these ‘rural towns’ are growing is unprecedented — for example, annual growth rates in excess of 5% are typical in urban agglomerations in Sub-Saharan Africa (UN-Habitat, 2005). The existence of different government structures (even in the same geographical region) adds to this complexity, such that caution is needed when making policy decisions based on national statistics. Within urban areas, the inter-urban differences in service levels are perhaps a better indicator of overall delivery.
