What does demic mean?
Demic is a technical adjective relating to a people or population, derived from the Greek word dēmos, meaning 'the people'. It appears almost exclusively in academic contexts, most notably in archaeology, anthropology, and population genetics. Its best-known use is in the phrase 'demic diffusion', which describes the spread of ideas, technologies, or languages through the physical migration of people themselves, as opposed to 'cultural diffusion', where traits pass between neighbouring groups without large-scale movement of populations. For example, scholars debate whether farming spread across Neolithic Europe primarily by demic diffusion — migrating farmers settling new land — or by indigenous communities adopting agricultural techniques from their neighbours. Because it is precise and unambiguous within its fields, demic is valued by specialists, though general readers will rarely encounter it outside scholarly literature on migration, ancestry, and population history.

Swap in a single letter and 'demic' goes from describing ancient human migrations to describing demons.

Etymology of demic
Demic derives from the ancient Greek dēmos, meaning 'people' or 'the populace', combined with the adjectival suffix -ic. It entered scholarly English usage in the nineteenth century alongside other terms built on the same root, such as 'democracy' and 'demographic'. Its modern prominence owes much to the geneticist Luigi Luca Cavalli-Sforza and colleagues, who popularised 'demic diffusion' in studies of prehistoric population movement. Cognates sharing the dēmos root include 'epidemic' and 'endemic', which originally concerned what is 'upon' or 'in' a people.
How demic is actually used
A technical term used chiefly in academic writing — anthropology, archaeology, genetics, and demography — and rare in everyday speech. It carries no strong connotation, positive or negative, but signals scholarly register.
