What Is a Composite Index?

A composite index is an indicator that changes a variety of values that cannot be measured in the same way to values that can be measured together, and then compares them to indicate the overall change in things. It is an index calculated by comparing two comprehensive aggregate indicators. Taking the product output index as an example, because various products have different use values and measurement units, they cannot be directly added for comparison; however, various products can be multiplied by their respective prices, that is: output × price = output value, and the amount of value Can be added and compared. The price here is called the same measure. For a total index composed of two or more factors, when calculating the total index, only one of the factors is changed and the other factors are fixed. The total index calculated from this is the comprehensive index. The general price index is a typical example of a composite index. ^[1]
