Research question
How can an older inflation analysis remain reproducible?
Source context
BLS technical notes describe CPI methods, including seasonal adjustment and revision practices.
Evidence record
Keep the source URL, series definition, publication date, reference period and adjustment basis.
Interpretation
A research publication date is not the same as the period measured by the data.
What to monitor
When updating a chart, document any change in source definition or historical observations.
Limitations
A record of provenance improves traceability; it does not eliminate measurement uncertainty. This note does not quote a current inflation estimate.
