Brazil - Industrial Production

This dataset is from Brazil's Monthly Industrial Survey of Physical Production, which provides short-term indicators of the volume of mining and manufacturing production.

Industries are based on the National Classification of Economic Activities (CNAE) in accordance with ISIC Rev.3. Seasonal adjustment was performed using the X-12 method.

Industry classifications are based on the National Classification of Economic Activities (CNAE), which is the localization of ISIC Rev.3.

The dataset has undergone two major revisions since it's inception. The earliest data runs from January 1985 to January 2004 and is indexed to base year 1995. In April 2004, the survey was revised. This second revision runs from January 19991 to February 2014 and is indexed to base year 2002. It has been replaced by the most recent revision, which is being actively updated, is indexed to 2012, and begins in January 2002

The actively updated (2012=100) series is comparable to the discontinued (2002=100) series because they were created with the same revised methodology. The earliest dataset (1991=100) is not comparable to the other two datasets because it was collected using the pre-revision methodology.

In the selection of products and respondents, intentional sampling was used, based on the variable Value of Production of products in the Annual Survey of Mining and Manufacturing Industry - Product Statistics (1998), so as to obtain a representative sample of at least 50 percent of the industrial universe. According to the Value Added variable in the 1998/2000 period, the coverages obtained per geographic unit were as follows: Brazil (63%), Amazonas State - 38 products (72%); Pará State - 23 products (73%); Northeast Region - 162 products (62%); Ceará State - 62 products (61%); Pernambuco State - 76 products (50%); Bahia State - 79 products (66%); Minas Gerais State - 143 products (64%); Espírito Santo State - 24 products (71%); Rio de Janeiro State - 137 products (56%); São Paulo State - 490 products (55%); Paraná State - 136 products (52%); Santa Catarina State - 113 products (50%); Rio Grande do Sul State - 197 products (55%) and Goiás State - 49 products (46%).

The regularly released indices are subject to revisions, i.e. indices are subject to adjustments up to the first month of the year preceding the reference year. This procedure is described in the methodological notes that accompany the dissemination of the indices. Comments on revisions of a methodological nature are included in these methodological notes of monthly releases. The last methodological revision was based on the results of the Annual Survey of Mining and Manufacturing Industry and also on the results of the Annual Survey of Mining and Manufacturing Industry – Product Statistics for 1998/2000. New data series is beginning in January, 2002 and the linking to historical index is for 1991 onward.

Data is monthly, and is released with an average lag of 40 days after the reference month.
