While the total number of households is correct, the estimate for households with social security income is much lower in IPUMS than in the ACS SF. Normally, PUMS data are within the margin of error of SF data. Could there be a problem with my syntax or is there an issue with INCSS?
Here is the SPSS syntax I used:
COMPUTE filter_=(RELATE = 1). FILTER BY filter_.
WEIGHT BY HHWT.
