In response, we have archived the two groups of predecessors (1998=100, January 1979 to December 2016; July 1999=100, December 2002 to December 2016) by renaming with an "_98" or "_99" specifier, by marking metadata as "discontinued," and by segregating in the catalog. The replacements (2015=100) have an unchanged start date. Most of the series are reported as not seasonally adjusted (NSA).

The active series reside in the historical catalog (Norway » Price » Consumer price index » 2015=100) and the predecessors under the associated "discontinued" node. They include, for example:

• CPITT_98AM.INOR = [DISCONTINUED] Consumer price index: All items, (1998=100, SA)
• CPITTAM.INOR    = Consumer price index: All items, (2015=100, SA)
• CPIABTUM.INOR   = Alcoholic beverages and tobacco [02], (2015=100, NSA)
• CPIIRHUM.INOR   = Imputed rentals for housing [04.2], (2015=100, NSA)
• CPITRAUM.INOR   = CPI-AT - Transport, (2015=100, 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 "CPI-AE" excludes energy products.
• The "CPI-AEL" excludes electricity.
• The "CPI-AT" is adjusted for tax changes.
• The "CPI-ATE" is adjusted for tax changes and excludes energy products.
• Although the source reports a SA version of the all-items index, it starts at January 1985. We have extended it to March 1920 by using compatible series.
