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.
The term demographics is often used erroneously for demography, the study of human population and its structure and change.Whereas demography is a descriptive and predictive science, demographics is an applied art and science. In both cases however, the objects of study are the characteristics of human populations.n the case of demography the characteristics being studied tend to emphasize biological processes such as population dynamics, whereas demographics is also concerned with a wide range of economic, social, and cultural characteristics.
