Table explanation
Changes as of June 22nd 2018:
Statistics Netherlands has carried out a revision of the national accounts. New statistical sources and estimation methods have been used during the revision. Therefore this table has been replaced by table Employment; economic activity, quarterly, National Accounts. For further information see section 3.

In response, we have:

1. Archived the predecessors (1995Q1 to 2018Q1) by renaming with an "_18" specifier, by marking metadata as "discontinued," and by segregating in the catalog.
2. Created one-for-one replacements. They start at 1995, and properties are otherwise unchanged.

The active series reside in the historical catalog (National Accounts » Branch accounts » Employment » Quarterly » SIC 2008) and the predecessors under the associated "discontinued" node. They include, for example:

• NAQEMT_18UQ.INLD = [DISCONTINUED] All economic activities [A to U], (Ths. #, NSA)
• NAQEMTUQ.INLD    = All economic activities [A to U], (Ths. #, NSA)
• NAQEMMFAQ.INLD   = Manufacturing [C], (Ths. #, SA)

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.
