CPS multiple jobholding: indexing second jobs without rewriting the household frame
The Current Population Survey (CPS) publishes multiple jobholding rates that count people who held more than one job during the reference week. Spool Pad treats that series as an index strip: a thin label on the wider household employment recording—not a rewrite of how families should allocate hours.
What the rate indexes
BLS summaries of multiple jobholding typically report the share of employed people with more than one job, sometimes broken out by full-time versus part-time on the primary job. The construct depends on self-report of job count in the survey week. Secondary jobs may be wage, salary or self-employment arranged in different ways.
What the label does not carry
- It does not by itself measure annual secondary earnings intensity.
- It does not separate gig-platform receipts from other second jobs unless paired with other modules.
- Month-to-month volatility can reflect sampling and seasonality as much as structural change.
Why the frame stays intact
Household income frames in other surveys (for example annual income modules) ask different questions over different periods. Comparing a weekly multiple-jobholding flag to annual secondary earnings requires careful bridging. Spool Pad keeps those instruments on separate tracks rather than merging them into a single “side income” story.
What this note does not claim
This track does not tell readers to take a second job, does not estimate typical pay and does not interpret the CPS rate as evidence about any individual’s situation. It only describes how a named public series indexes multiple jobholding beside the primary employment frame.
