An error related to the scope of the survey was found in the text of the Technical Note. The text informed that the enterprises covered should have “at least one person employed on December 31 in the reference year of the basic register of the survey”. That sentence was taken out of the document. The other error was found in the calculation of the estimates, where three components of the vector associated to the calibration factor are imprecisely defined. The definition was rewritten in the corrected version.
Actions: The Technical Note of the survey was amended and replaced on the IBGE website.
