demográfica

Demográfica is the feminine form of the adjective demográfico in Spanish and Portuguese. It is used to describe aspects related to demografía or demografía, the study of populations, their size, structure, distribution, and changes over time. The term appears in phrases that refer to population characteristics, rather than a standalone concept.

Etymology and usage notes: the word derives from the Greek demos (people) and graphein (to write) through Latin demographia, and entered the modern languages as demografía, demográfico, and demográfica. In contemporary usage, demográfica agrees in gender with the nouns it modifies, such as población demográfica or distribución demográfica.

Common uses: examples include la distribución demográfica de una región, la estructura demográfica de la población, o políticas demográficas. The feminine form is required when the noun is feminine (for instance, población, distribución, clase). In masculine contexts, the corresponding form is demográfico (por ejemplo, cambio demográfico, grupo demográfico, datos demográficos).

Relation to the field: demográfica is a grammatical inflection rather than a separate field. The related noun is demografía, and its study encompasses population size, age and sex composition, birth and death rates, migration, and population aging. The term appears across social sciences, urban planning, marketing, and public policy.
