| Description | Standardization is a technique applied to compare indicators between groups when differences in group characteristics affect the comparison. It uses the fact that the indicator of interest can be computed as a function of characteristic-specific indicators, and produces the so-called standardized indicators, which are adjusted to differences in group characteristics. For instance, crude death rate is a sum of age-specific death rates multiplied by their respective age-group proportions. Age-standardized death rate is obtained by using a common (standard) age structure for the populations compared while keeping their age-specific rates as observed. Decomposition takes the procedure one step further: It allocates the difference between the crude indicators into composition- and indicator-related components. |
