I am working on the 1980-2010 Brazilian censuses and I have two questions about their geographical variables.
First, I have read that geographical variables have been revised for many countries since the recent data release in October 2015. Does this also concern Brazil (and in particular the variable MUNIBR)?
Second, I want to be sure I have understood properly the difference between the old geographic harmonization implemented by IPUMS (by name) and the new one (using GIS files). Let’s take the example of a municipality. The only way the two harmonizations can differ is when the boundaries of a municipality have changed without involving a merger with some other ones or a division into other ones (ie. without involving the creation or the disappearance of some administrative municipalities). Am I correct?
Thank you for your help,
