Abstract

The quantitative study of fecundity, mortality and population movements, and the analysis of social areas in urban environments, can be used as a tool to draw up a diagnostic of the sociodemographic of cities. The availability and the depth of municipal detail contained in information obtained from national and/or regional statistical institutions means that the Census of Population and Housing, the Natural Movement of Population and the Continuous Register can be used as sources of reference in studies of this type. The city of Valencia is used as an example for a demographic study of recent changes in birth rates, population aging and migration. On a space of reduced dimensions, specific thematic maps delimit the social areas involved and show the inequalities in the distribution of the socioeconomic status and the life cycle of the resident population and foreigners
