Slide Rule

Independent notes on how household surveys, labour-force modules and related instruments gauge platform work and secondary earnings

A measurement desk: named sources, visible method limits, and no assumption about any reader’s circumstances.

On this scale

Three reading lines

Notes review published survey instruments and research papers, not income playbooks. Focus stays on definitions, sample frames and observation bias.

Household supplements, administrative tax records and international measurement frameworks are compared with methodological critique in the same text.

Slide Rule does not publish testimonials, reviews or outcome stories. The desk describes how others measure; it does not prescribe conduct or forecast effects.

Editorial criteria

  • No presupposition about the reader. Slide Rule does not claim or imply knowledge of any visitor’s personal, labor or financial situation.
  • Named source or no claim. Every figure or pattern is attributed to an identifiable study, supplement or guideline. Contested evidence is marked as contested in the same paragraph.
  • Method critique on the page. Each note states sample, definition or coverage limits; findings are not presented as universal conclusions.
  • No outcome framing. Content is not described as a system, protocol or sequence that produces income, employment or a change of condition.
