The AoI of all capitals were found to be far larger than the MC area, with large fringe areas lying outside the MC boundaries. When the fringe areas are taken into account, Sri Lanka’s the populations of the Provincial Capitals were far larger than official statistics suggests. In all cases, the fringe population was more than double the size of the MC population. In the case of Colombo the fringe of the agglomerated MCs of Colombo, Kotte and Dehiwala accounted for an estimated 2.3 million people, resulting in a total estimated population of 3.17 million people in the Colombo AoI. If the CMR (i.e. the Western Province) is included as the total urban area, then the city’s population doubles again. These results strongly suggest that city boundaries need to revised, and appropriately demarcated, to enable evidence-based urban planning. In the cases of Colombo, the definition of the city extent varies between 550,000 and over 6 million: the urban management implications for these different definitions are highly significant, particularly in terms of the delivery of public services (see Chapter 6).
