Complexity refers to the relationship between the urban system and its environment, and is a measure of the levels of diversity and organization in an urban system. Moreover, urban complexity is a reflection of the interactions between economic activities, associations, facilities and institutions.
Complexity is linked to a mixture of order and disorder in urban systems and can be analyzed, in part, by making use of the concept of diversity. Living organisms, people, and their organizations, are carriers of information who accumulate knowledge and hold the capacity to significantly influence the present and control the future.
Urban strategies that increase the diversity index are those that seek a balance between urban uses and their functions. It is, among other objectives, meant to bring people to services and jobs, to increase employment and reduce energy consumption. Indicators such as employment and self employment make it possible to determine the proximity between residence and work.
Over time, indicators of complexity (diversity) show the development of the urban fabric and the wealth of economic capital, social capital and biological capital will grow.
