ABSTRACT
COMPUTERIZED Demographic analysis system includes the sets of methods that allow us to measure the dimensions and dynamics of populations. These methods have primarily been developed to study human populations, but are extended to a variety of areas where researchers want to know how populations of social actors can change across time through processes of birth, death, and migration. In the context of human biological populations demographic analysis uses administrative records to develop an independent estimate of the population. Computerized Demographic analysis system estimates are often considered a reliable standard for judging the accuracy of the census information gathered at any time. In the labor force demographic analysis is used to estimate sizes and flows of populations of workers; in population ecology the focus is on the birth, death and movement of firms and institutional forms.
