  • Revision of seasonal adjustment in 2014
    RegARIMA models have been updated when revising seasonally adjusted data retroactively on the release of January 2014 results. Fifteen of seasonally adjusted series by industry will be discontinued on the release of April 2014 results, because no substantial seasonality was observed over the past decade except two retained series: "Agriculture and forestry" and "Non-agricultural industries".

  • Change in "Historical data 1"
    "Historical data 1" has been renewed on the release of January 2014 by putting major series together into one Excel book and adding three new original (non-seasonally adjusted) series: "Population aged 15 years old and over", "Not in labour force", and "Employment rate" by age group. Please be aware that the filenames of all the Excel books in "Historical data 1" have been altered.
