Hello! I was wondering if the crosswalks for the official IBGE codes are available for 1960 and 1970 as well (those for 1980, 1991, 2000, and 2010 have previously been shared on this thread). Thank you so much!
You can find the harmonization table giving the correspondence between the original codes and IPUMS codes for 1970 by visiting the codes page and clicking on “Explore How IPUMS Created This Variable” link at the bottom. For 1960, the original codes can be found in the source variable BR1960A_0017, though there are no labels available.
