Motivation: Our national source, the Brazilian Institute of Geography and Statistics (IBGE), reports nominal gross value added , but only in not seasonally adjusted (NSA) terms.

Response: For analytical consistency, we have created seasonally adjusted (SA) counterparts.

Properties: The start date (1995Q1) and units are identical for the two versions. Expect our SA series to be revised with each update. Supplemental series of this kind are marked in their source metadata with a secondary citation of "Moody's Analytics Adjusted."

The series reside in the historical catalog (Brazil » National Accounts » by Value Add » Quarterly » Current prices) and are, for example:

• NALSGVAAFAQ.IBRA = National accounts: Production approach - Gross value added at basic prices - Agriculture, (Mil. BRL, SAAR)
• NALSGVAMQAQ.IBRA = National accounts: Production approach - Gross value added at basic prices - Mining, (Mil. BRL, SAAR)

Method:

1. Adjust reported industry detail using the U.S. Census Bureau's X-13 ARIMA program.
2. Compute Industry, Service, Total Gross Value Added and GDP aggregates as identities.
