demography

The term demography is a modern scientific compound formed from two ancient Greek roots. The first, dēmos, originally referred to a district, its people, or the common populace. The second, -graphia, denotes the process or result of writing, recording, or describing. Combined, they create a word whose literal meaning is "the writing about or description of the people." This etymological logic maps directly onto the modern academic discipline, which systematically records, describes, and analyzes the statistical data of human populations. The concept evolved from simple descriptive accounts to a rigorous social science that studies the dynamics of population change, structure, and trends.

Structure: demo (people) + graphy (writing/study of) - demo: From Greek dēmos, meaning "people, populace." - graphy: From Greek -graphia, meaning "writing, description, or study of," from graphein, "to write."
