Seasonal adjustment of Labour Force Survey time series with the TRAMO/SEATS method

A new seasonal adjustment method was introduced in the Labour Force Survey on 19 June 2007. The new method is the TRAMO/SEATS method applied with Demetra software as recommended by Eurostat. The method used prior to this was X11-Arima.

The changeover to the new seasonal adjustment method will not affect the interpretation and use of seasonally adjusted series from the Labour Force Survey. The results obtained with the TRAMO/SEATS method will not essentially deviate from those obtained with the previously used X11-ARIMA method. Trend will continue to be the reported result from the seasonal adjustment.
