Adjusted rates or standardized rates help remove the effects of differences in composition of various populations (for example, age differences).
Direct Adjusted Rates - age specific rates observed in 2 or more study populations are applied to an arbitrarily chosen standard population.
Indirect rate adjustment - compares 2 or more populations in which the age-specific rates are not known or are excessively variable because of the small size of the population. In this case, the rates of the more stable population are applied to the population of the smaller group.
