What is seasonal adjustment?

Seasonal adjustment is a statistical technique that eliminates the influence of recurring seasonal events such as weather, holidays, and the opening and closing of schools from economic data series. This allows for easier observation and analysis of nonseasonal changes in the data. By eliminating seasonal fluctuations, the data series become smoother and it is easier to compare data from month to month. Removal of seasonal fluctuations facilitates analysis of economic business cycles.
