Syn: age adjustment. Mathematical procedures for adjusting rates in two or more populations with differing age structure so as to adjust for rate differences among them that are or could be attributable to the effect of age differences, rather than other factors. Direct and indirect methods are available, involving mathematical calculations. For a description of the direct method, see http://www.cdc.gov/nchs/datawh/nchsdefs/ageadjustment.htm. See also standardization.
