What Does definition of demography Mean?
At its core, the definition of demography names a field, not a single answer. Demography studies births, deaths, marriages, migrations, aging patterns, and the statistical relationships between them. Those numbers tell a story about how societies change, who moves where, and which generations will shape politics and markets.
Etymology and Origin of definition of demography
The word demography comes from Greek roots: demos meaning people, and grapho meaning to write. The term entered English in the 19th century as scholars began systematically measuring population phenomena. Early demographers, like Thomas Malthus and later the pioneers of vital statistics, framed many questions we still ask today.
