In economics, the absence rate is the ratio of workers with absences to total full-time wage and salary employment. In the United States, absences are defined as instances when persons who usually work 35 or more hours per week worked less than 35 hours during the reference week for one of the following reasons: own illness, injury, or medical problems; childcare problems; other family or personal obligations; civic or military duty; and maternity or paternity leave.
