Data Change: Germany - GDP(E) - Re-referenced to 2015
Thursday, 12 Sep 2019 10:07 ET
By Ferdinand Loessl
September 2019 –- For the quarterly national accounts of Germany, including the expenditure approach to GDP, concurrent with dissemination of results for 2019Q2, the source has advanced the currency reference year from 2010 to 2015 and conducted the five-year general revision (260 quarterly series 1991 to 2019, replaced by 260 from 1991).

On 27 August, the source wrote (citation, pdf):

Generalrevision der Volkswirtschaftlichen Gesamtrechnungen 2019
4. Warum werden Ergebnisse in den Volkswirtschaftlichen Gesamtrechnungen revidiert?
Zudem wurden im Rahmen der Revision die realen Ergebnisse auf das neue Referenzjahr 2015 umgestellt.

That is:

General Revision of National Accounts 2019
4. Why are results in national accounts revised?
[...] In national accounts, calculations are generally revised every five years. This revision is required to introduce new concepts, classifications, definitions, calculation methods and data sources. To avoid breaks in the time series as far as possible, the results for Germany are recalculated until 1991.
In addition, in the context of the revision, the real results were changed to the new reference year 2015. 

In response, we have:

  1. Achieved the predecessor series (currency reference year 2010, 1991Q1 to 2019Q1) by renaming with an "_10" specifier, marking metadata as "discontinued", and segregating in the catalog.
  2. Created one-for-one replacements (reference 2015), which have an unchanged start date.
  3. Replaced the current-value series in the same way.
  4. Refurbished the catalog.

Dataset properties:

  • Framework: ESA 2010 
  • Measurements:
    • Billions of euros at current prices (Bil. EUR)
    • At constant year-2015 prices (Bil. 2015 EUR)
    • At chained year-2015 prices (Bil. Ch. 2015 EUR)
    • Chain-linked volume index (Ch. Vol. Index 2015=100)
  • Adjustments:
    • Not seasonally unadjusted (NSA)
    • Calendar day adjusted and seasonally adjusted (CDASA)
    • Calendar day adjusted and seasonally adjusted using BV4.1 (CDASA BV4.1)
  • Geo coverage: Country
  • Native frequency: Quarterly
  • Start date: 1991Q1

The active series reside in the historical catalog (Germany » National Accounts » By expenditure » Quarterly » Chained prices | Current prices | Chained index | Volume index) and the predecessors under the associated discontinued node (... » Quarterly » Ref 2010). They include, for example:

  • NACEFCHN_10UQ.IDEU     = [DISCONTINUED] National accounts: Expenditure approach - Final consumption expenditure - Households and NPISHs, (Bil. 2010 EUR, NSA)
  • NACEGFCFMEPE_10UQ.IDEU = [DISCONTINUED] Gross fixed capital formation - Machinery and equipment - Non-government sectors, (Bil. 2010 EUR, NSA)
  • NACEFCHNUQ.IDEU        = Final consumption expenditure - Households and NPISHs, (Bil. 2015 EUR, NSA)
  • NACEGFCFMEPEUQ.IDEU    = Gross fixed capital formation - Machinery and equipment - Non-government sectors, (Bil. 2015 EUR, NSA)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.

Please be aware that

The source reports alternative seasonal adjustments using three different programs: X-12 ARIMA (U.S. Census Bureau), JDemetra+ (National Bank of Belgium), and BV4.1 (FSO of Germany).
