Questions to carry forward
- Why do CPI and labor statistics require different samples?
- What changes when a person moves outside the labor force?
Claim disciplineEvidence boundaries
- No one BLS series captures every household price experience, labor condition, or worker outcome; current definitions and release notes control use.
BLS is not merely a website that publishes percentages. It maintains classification, sampling, seasonal-adjustment, and revision systems. A 4% unemployment rate and 4% price change share typography but not a denominator.
The agency entry teaches source hierarchy. Use the current definitions and the dated release for a measurement claim; use an institutional history only for the agency's evolution.
