BLS Contingent Worker Supplement: depth marks beside the main job reading
What the CWS asks about contingent and alternative work, and where secondary earnings can sit outside the primary survey slots.
Depth Slate
A measurement log for method: named sources, visible coverage limits, and no assumption about any reader’s circumstances.

On this slate
Notes review published instruments and papers on secondary jobs, platform-mediated work and how household surveys record those flows—not income playbooks.
Household surveys, administrative records and international measurement guidance are compared with methodological critique in the same text.
Depth Slate does not publish testimonials, reviews or outcome stories. The slate describes how others measure; it does not prescribe conduct or forecast effects.
