Behavioral Risk Factor Survey
Age Adjustment

Age adjustment is the application of age-specific percentages in a population of interest to a standardized age distribution. It enhances the comparability of populations by controlling for the effects of their differing age compositions. The age-adjusted percentage for a population of interest can be compared to that of a different age-adjusted population at the same point in time or the same population at a different point in time.

Age-adjusted percentages in the Behavioral Risk Factor Survey modules are calculated using the direct method based on the year 2000 U.S. standard population.
