Users can access the microdata collected in these household surveys. For each year, there is a data file for each unit of the federation (state). Until 1991, there was only one file for both household and individual characteristics. Since 2000, there is one file for each type of record.
The package prepared by Data Zoom applies to the 1970, 1980, 1991, 2000 and 2010 rounds of the Census. It provides a tool for reading the microdata through STATA, generating STATA format files (.dta). All variables are named after IBGE dictionaries (the Portal provides an English version of the original dictionaries for download). In order to be able to use the package, the user must first obtain the microdata related to the rounds she is interested in. DataZoom does not provide these data. The 2000 and 2010 microdata and documentation are available for download from the IBGE website at this link. For information on how to acquire other rounds, click here.
Because of methodological changes made by IBGE over the years, the same information may not be available every year and/or may not have been collected in the same way. Data Zoom offers an option to manipulate the variables subject to compatibility in order to standardize information over time. In this case, variable names are not the ones suggested by the original dictionary and a new dictionary is provided for download. The document entitled Making Census Compatible explains all the procedures adopted in the process.
In 2010 survey, microdata for 14 municipalities were corrected, thus two new files were released for the observations reviewed. It is necessary to download, in addition to the file containing the microdata, the following file "microdados_14_municipios_com_areas_redefinidas_20160331" available at this link and adds it to the same folder where the microdata is located on your computer.
