Note: Seasonally adjusted estimates by class of customer will not be produced.
Due to the shortness of the series, seasonally adjusted estimates will be published only for QSS series with indications of a good quality seasonal adjustment. However, research will continue on the seasonal adjustment of additional series.
Yes, part of the Annual Benchmark Report, seasonally adjusted estimates will be provided for all quarters for which there are unadjusted estimates available. The quarterly press release contains seasonally adjusted estimates for the most recent six quarters.
Seasonal adjustment is the process of estimating and removing seasonal effects from a time series in order to better reveal certain non-seasonal features. An example of a seasonal effect is an increase in accounting services during the tax season. (Seasonal effects are defined more precisely below.)
Seasonal movements are often large enough that they mask other characteristics of the data that are of interest to analysts who track current economic trends. For example, if each quarter has a different seasonal tendency toward high or low values it can be difficult to detect the general direction of a time series' recent quarterly movement (increase, decrease, turning point, no change, consistency with another economic indicator, etc.). Seasonal adjustment produces data in which the values of neighboring quarters are usually easier to compare. Many data users prefer seasonally adjusted data because they want to see those characteristics that seasonal movements tend to mask, especially changes in the direction of the series.
Seasonal adjustment procedures for quarterly time series estimate effects that occur in the same calendar quarter with similar magnitude and direction from year to year. Examples of these effects include economic activity tied to the tax season or to the travel season. The seasonal factors are estimates of average effects for each quarter. It is important to note that seasonal factors are based on present and past experience and that future data may show a different pattern of seasonal factors.
We use X-13ARIMA-SEATS to derive our seasonal adjustment and produce seasonal factors. X-13ARIMA-SEATS is a seasonal adjustment program developed at the U.S. Census Bureau in collaboration with the Bank of Spain that integrates an enhanced version of X-12-ARIMA with an enhanced version of SEATS to provide both X-11 method seasonal adjustments and ARIMA model-based seasonal adjustments and diagnostic.
QSS estimates are adjusted using the X-11 filter-based adjustment procedure.
We currently use version 1.1, build 10 of X-13ARIMA-SEATS.
