I’m using SPSS to calculate median household income for detailed Asian groups, but also ran numbers for White, Black, Asian, and Hispanic groups so I could check my numbers against published Census data. I’ve read forum discussions explaining why IPUMS USA samples will vary from the ACS datasets used by the Census, but my results were considerably outside the error margins.:
White (my result) 71,210; (census figure) 69,823
Black (my result) 44,500; (census figure) 43,862
Asian (my result) 96,500; (census figure) 93,759
Hispanic (my result) 58,000; (census figure) 55,658
Following advice in forum posts, I’ve selected cases where PERNUM=1 & GQ<3 & HHINCOME [not equal to] 9999999, and then selected for the relevant racial group (e.g., RACE=1 & HISPAN=0 for non-Hispanic White).
Is there something else I’m missing, or can this much variance be due to differences in sample? Thanks.
