The Monthly Employment Survey (PME), released monthly by the Brazilian Institute of Geography and Statistics (IBGE) since 1980, and recognized as the main source of information about the Brazilian labor market, was discontinued in 2016. It was replaced by the National Survey by Continuous Household Sample (PNADC), nationwide and also released by that institute. The replacement of PME by PNADC created numerous difficulties related to the continuity of the series. The study presented here aims to circumvent the problem of the relatively limited time span of the new PNADC series, started in March 2012. Using data from the PME and another job survey released by IBGE - the National Household Sample Survey (PNAD) - we developed a PNADC retropolation method, which allows us to produce longer time series. While the original data can be used only since March 2012, the new series are estimated back to September 1992. With the new retropolation method, it is possible not only to circumvent the problem of the inability to generate long series for the PNADC, but also provide an important tool for understanding the historical behavior of employment and income nationally.
