I am calculating Gini coefficients for the universe of places using 5-year ACS estimates (2008-2012). The calculation requires the number of households per place in each income category and the mean income of each category. I am using the Census Bureau data aggregated by place to estimate the number of households in each category. In order to more precisely estimate the mean value of each household income category, I would like to use the microdata.
The page describing IPUMS adjustment techniques indicates that IPUMS pre-applied the Census Bureau’s adjustment factors to FTOTINC “[b]etween November 2009 and March 2010.” It’s not clear what the practice has been since March 2010.
Is the IPUMS FTOTINC variable for the 2008-2012 5-year sample calculated using the same adjustments as the aggregate ACS data provided by the Census Bureau?
