4 Variable in the 2016 ATUS sample don’t appear to have been recoded for NIUs
SCC_HHNHHOWN_LN
SCC_HH_LN
SCC_OWN_LN
SCCOWNHH_LN
All have some “-1” which I believe should actually be “9999” NIUs
Thought I posted this earlier – Sorry if this is a repeat question.
You are correct, these values of -1 should be 9999 “NIU”. I’ve sent a note to the IPUMS Time Use Team about this issue. This fix should show up online with the next data release, which is slated to be within the next few months. In the meantime, you can simply recode these values to NIU.
