Not only are financial and human resources often scarce, there is also low flexibility with respect to how resources are allocated and used. This is detrimental to a city’s ability to increase the quality of life for its residents. For example, an evaluation of 2011 sub-national financing dimensions relative to cities that scored in the top five for quality of life based on the Universidad Catolica's Quality of Life Index signals a moderate to strong correlation between higher rankings and a municipality’s ability to generate own-source income and the amount of income budgeted per resident (Table 4.1).
