Definition
This is the usual number of hours worked per week in the main job.
Use information from all sections (12 months or 7 days) that ask this question.
First use information from the 12 month section. For all missing values and observations coded as 9, use the 7 day section.
If only information on how many hours individuals worked per day is available but no information on number of days worked a week is available, multiply the hours by 5 days.
Similarly for hours worked per month divide by 4.2 to get weekly hours.
