Why does supp3wt variable have only zero values?

I need to use supp3wt (for several acivities in daily living variables in 1994 and 1995) but this weight variable seems to have only zero values.

. sum supp3wt if year==1994 | year==1995

Variable | Obs Mean Std. Dev. Min Max
supp3wt | 24,233 0 0 0 0

This is an error. Thanks for letting us know! I've informed the IPUMS Health Surveys team and it should be fixed with the next data release. In the meantime, I can email you a file that should provide you with the correct values for SUPP3WT for 1994 and 1995.
