Demography (from prefix demo- from Ancient Greek Î´á¿Î¼Î¿Ï dÄmos meaning the people, and -graphy from Î³ÏÎ¬ÏÏ graphÅ, implies writing, description or measurement) is the statistical study of populations, especially human beings.
Demographic analysis can cover whole societies, or groups defined by criteria such as education, nationality, religion, and ethnicity. Educational institutions usually treat demography as a field of sociology, though there are a number of independent demography departments.
