I can’t come close to replicating median household income (computed on full ACS microdata) using the ACS IPUMS sample. Using ACS IPUMs data, I find median household income of about $66,000 in 2015, whereas other sources using the ACS full microdata report that this number should be much lower, about $57,000. I am pretty sure that I am using the right weights (in fact, any weighting choice won’t close the gap). Restricting to non-group quarters, etc. don’t significantly affect this discrepancy. Does anyone know what could be going on here? The gap is huge.
