Meaning of Demography
What is Demographics:
Demography is a social science that studies the volume, growth and characteristics of a group of human population in a certain period of time or its evolution. It comes from the Greek δήμος (dēm (o), "town", "population") and γραφία (graphíā "trace", "description", "study", "written") and could be translated as "population study".
These are statistical studies relating, for example, to birth, mortality and migration. Official bodies are in charge of collecting this type of data and instruments such as surveys and registers are used.
