IBGE will release, on March 30, the new series of the Monthly Survey of Trade


With the release of indicators for January 2017, the IBGE starts a new series on the country's retail trade, taking as a base the year (1) 2014 = 100, which presents the following methodological revisions:

  • It updates the informant sample to 6150 enterprises6150 enterprises, selected from the certainty (enterprises with 20 or more employed persons) and managerial stratum of the Annual Survey of Trade - PAC 2014.

  • The indices from January 2000 to December 2003 take the year 2000 as base. The indices from January 2004 to December 2011 take the year 2003 as base. The indices from January 2012 until December 2016 take the year 2011 as base. The indices from January 2017 onwards take the year 2014 as base.

  • The complete series of the indexes (linked series) take as time reference (2) the year 2014.

    (1) Base-year: the year in which the weightings of the activities are used in the calculation of the indexes.
    (2) Reference period: the year for which the index equals 100. The replacement with the reference year involves a simple calculation and does not interfere in the series configuration.
