In response, we have archived the predecessors (as early as 2004 to 2015) by renaming with an "_15" specifier, by marking metadata as "discontinued," and by segregating in the catalog. The replacements have an unchanged start date. Geo coverage is the nation and all 16 NUTS level 1 and all 38 level 2 areas (under NUTS 2010).

The series reside in the historical catalog (Germany » Real Estate » Residential » Price » BulwienGesa AG) and include, for example:

• HP%BGTR_15UA.IDEU  = [DISCONTINUED] Price for residential units [unweighted average of houses and apartments], (% Y/Y)
• HP%BGTRYUA.IDEU    = Price for residential units [unweighted average of houses and apartments], (% Y/Y)
• HPLBGTRUA.IDEU_06  = Price for residential units [unweighted average of houses and apartments], (EUR) - for NUTS 1 Hessen
• HP%BGAFUA.IDEU_130 = Affordability index for residential units as multiple of average income, (Ratio) - for NUTS 2 Mecklenburg-Vorpommern

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

Please be aware that:

• We have standardized the mnemonics of the growth series by inserting a "Y" character (for year-over-year). You will need to amend legacy retrievals.
