Why Seasonal Adjustment - DRAFT

adjustments. Economists, policy makers, and consumers use time series we publish to make decisions. They try to identify important features of economic series such as direction, turning points, and consistency between other economic indicators. Sometimes seasonal movements can make these features difficult to see, so we publish economic series with the seasonal movements removed for those who prefer to view data without seasonal movements. In this paper we will explore seasonal movements, seasonal adjustment, and we'll take a look at some of the features of economic time series.
