Household labour-force surveys in the Current Population Survey tradition ask whether the respondent held more than one job during the reference week and, if so, how many hours belonged to the second job. Hour Caliper reads that module as a caliper opening: it can close on a named second job, and it can miss irregular spells that the respondent does not treat as a job.
What the jaws close on
The standard multiple-jobholding question is tied to a short reference week. Hours on the second job are collected when the respondent reports a second attachment. Technical notes published with each monthly CPS release name the universe and the edit rules. Those limits belong next to any rate later quoted as “the” second-job share of employment.
What stays outside
Occasional platform tasks, unpaid waiting, and work the respondent files as a hobby often sit outside the jaws. Arrangement modules such as the Contingent Worker Supplement ask a different object and cannot be stacked onto the multiple-jobholding rate without a documented crosswalk.
This desk does not convert a second-job share into a personal hours plan. Corrections: support@hourcaliper.online.
