Data Zoom provides Stata codes for reading and organizing microdata from IBGE's household surveys. Data Zoom free packages contain dictionaries that enable processing the original data and generating files on Stata (.dta format). The program also provides tools that help researchers standardize surveys across time, build panel databases and deflate nominal variables. To use Data Zoom, the only requirement is to have the original data and Stata 12 (or later) installed on your computer. The programs were developed for Stata's version 12 for Windows.
