A pattern was realized where either 116 or 127 data points exhibit data outside the boundaries of known data labels.  This is a list of variables that fall under that description:
wprks
wpayu
wtrns
jobs

Others where roughly 0.1% of the data does not have labels and appears to be due to transcribing error:
