Cities evolve over countless years, each moment of change building up to larger societal and architectural shifts. Metropolises across the world are constantly subject to social, political, economic, or environmental forces that alter their fundamental identity - a character that is meant to be dynamic. As cities develop in size and impact, advancements in the understanding of cities and urbanism grow more complex.
Cities are formed from a sequence of narratives, characteristics, relations, and socio-spatial values that reflect the identity of the place. The livelihood of the city also depends on its people and a mutual relationship with them. Along with their communities and their circumstances, cities morph to reflect their residents' needs and values.
