Demography is the statistical study of human populations with reference to size and density, distribution, and vital statistics. Demographic statistics provide information about significant characteristics of a population that influence community needs and the delivery of health care services. Demographic studies provide descriptions and comparisons of populations according to the characteristics of age; race; sex; socioeconomic status; geographic distribution; and birth, death, marriage, and divorce patterns. These studies often have health implications that may or may not be addressed by the investigators.
