Carroll & Hannan (2000) view of organizational demography --
Demography has an institutionalized set of methodological procedures. These methods are not ends in and of themselves. They serve as tools for producing reliable empirical facts that inform a particular way of looking at research questions and developing theory. When used properly, demography yields unique and deep insights into social phenomena. (2000, p 17)

Organizing Principles of Demographics (Carroll & Hannan, 2000, p 25) --
Demography adopts a population perspective. As opposed to analyzing individual firms, demography seeks to explain properties of populations such as their composition (e.g. age distribution) or they dynamics (e.g. growth rates).
