Data Change: France subnational - HPI - Rebased to 2015 [UDPATED]
Friday, 28 Dec 2018 17:56 ET
By Victoria Donu
October 2018 -- For the detailed house price index for existing houses and apartments for France, concurrent with dissemination of results for 2018Q2, the source has advanced the base year from 2010 to 2015 (110 quarterly series 1994 to 2018, replaced by 128 from 1994). [Updated 28 December 2018.]

The source wrote (citation):

[...] second-hand dwellings prices indices are now published in a new version. Their elaboration is based on a revised and improved method of calculation. The scope has been extended to the overseas departments and is now France (excluding Mayotte). This new method is applied from the revised publication of Q1 2018. The reference is from now on the average in 2015 (against T1 2010 until the publication of T1 2018).

In response, we have:

  1. Archived the predecessors (2010=100, 1994Q1 to 2018Q1) by renaming with an "_10" specifier, marking metadata as "discontinued", and segregating in the catalog.
  2. Created one-to-one replacements (2015=100).
  3. Created the newly-added reporting areas and detail.
  4. Assigned standard mnemonics to the replacements.

Dataset properties:

  • Measurement: Fixed-base index relative to 2015Q1 (Index 2015Q1=100)
  • Adjustment: Not seasonally adjusted (NSA) and seasonally adjusted (SA)
  • Geo coverage:
    • INSEE regions (6 of 18)
    • INSEE départments (8 of 101)
    • INSEE metropolitan areas (3)
    • Other (6)
  • Native frequency: Quarterly
  • Start date: 1994Q1 (unchanged)
  • Subject to revisions: Yes
  • Lag: 90 days

The active series reside in the historical catalog (France » Real estate » Residential » House price index » INSEE » 2015Q1=100) and predecessors are located under the associated "discontinued" node. The include, for example:

  • HPIXAPT_10UQ.IFRA_IF = [DISCONTINUED] Existing apartments, (Index 2010Q1=100, NSA) - for NUTS 2 Ile-de-France
  • HPIX_10AQ.IFRA_SSD   = [DISCONTINUED] Existing buildings - for NUTS 3 Seine St Denis
  • HPIXAPTZ1UQ.IFRA_XMY = Existing flats - Conurbations greater than 10 Ths., (Index 2015Q1=100, NSA) - for France excl. Mayotte and Other
  • HPIXHOUAQ.IFRA_XDOM  = Existing houses, (Index 2015Q1=100, SA) - for France excl. overseas territories and Undefined Areas

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.
