demographic (adj.)

1891, from demography + -ic. As a noun, by 1998, short for demographic group or category. Related: Demographical; demographically.

demography (n.)

1880, from Gk. demos "people" (see demotic) + -graphy.

-graphy

word-forming element meaning "process of writing or recording" or "a writing, recording, or description," from French or Ger. -graphie, from Gk. -graphia "description of," from graphein "write, express by written characters," earlier "to draw, represent by lines drawn," originally "to scrape, scratch" (on clay tablets with a stylus), from PIE root *gerbh- "to scratch, carve" (see carve). In modern use, especially in forming names of descriptive sciences.

-ic

adjective suffix, "having to do with, having the nature of, being, made of, caused by, similar to" (in chemistry, indicating a higher valence than names in -ous), from French -ique and directly from Latin -icus, which in many cases represents Greek -ikos "in the manner of; pertaining to." From PIE *-(i)ko, which also yielded Slavic -isku, adjectival suffix indicating origin, the source of the -sky (Russian -skii) in many surnames.
