NHIS work arrangement variable

Hi IPUMS,

I’m looking at the WRKARRNG variable and wondering what happened to temp agency workers between 2010 and 2015. And likewise to regular, standard employees.

Also, given that the item is asked to adults aged 18+ who are currently employed or were employed during the last 12-month period, are NIU those who were out of the labor force (or not employed at all) during the reference period? Could you please clarify the definitions of NIU as well as the regular, standard employees? Thanks!
