Work loss days, past 12 months


WLDAYR is a 3-digit numeric variable.

130: Top code for 130+ days (2019-forward)
996: NIU (not in universe)
997: Unknown-refused
998: Unknown-not ascertained
999: Unknown-don't know


WLDAYR reports the number of days the respondent missed work because of an illness or injury in the last 12 months. Responses were reported as a value between 0 and 366. Beginning in 2019, responses are top-coded at 130 (130+ days). Absence due to maternity or paternity leave was not included.

The 1997 Field Representative's Manual describes work loss day as missing more than one-half of the usual work day from a job or business because of illness or injury. Interviewers were instructed to "always probe for an exact number. If the sample adult reports a range or interval, assist the sample adult in making an estimate by probing. For example, you might ask 'Could you give me a more exact number?'"

The universe for this question includes those who worked without pay.


Prior to 2019 WLDAYR is fully comparable over time. Beginning in 2019 WLDAYR is top-coded at 130 (130+ days).

The NHIS questionnaire was substantially redesigned in 2019 to introduce a different data collection structure and new content. For more information on changes in terminology, universes, and data collection methods beginning in 2019, please see the user note.
