BLS CPI / monthly context
Compare nine official U.S. city-average CPI series over their published monthly coverage. Missing observations remain visible. Price movements provide context, not evidence of competitive harm by themselves.
Comparison passport
Reviewed context bridges
Broad rent paid by tenants is attached as consumer-price context for the housing dossier; it is not a rent-setting market definition or a measure of housing supply, landlord concentration, or market power.
Consumer airline fares are broad transportation-price context for the airline dossier; they do not identify route markets, airline margins, capacity effects, or competitive causation.
The BLS internet-services item is broad household price context for the fixed-broadband dossier; it is not equivalent to the FCC broadband screen, a service-quality measure, or a legal market.
Wireless telephone service prices are broad consumer context for the mobile-wireless dossier; they do not measure plan quality, device subsidies, carrier profitability, switching, or market power.
Retail prescription-drug prices are attached as consumer context for the PBM dossier; they do not measure PBM services, rebates, spreads, pharmacy reimbursement, margins, or competitive effects.
The BLS health-insurance index uses its own retained-earnings method and is not a premium index. It is broad context for the individual-insurance dossier, not a measure of insurer concentration, plan generosity, or market power.
Food-at-home prices are broad grocery context for the meatpacking dossier; they do not isolate meat, cattle, processor margins, retailer margins, pass-through, or market power.
Interpretation standard
Computed from the current and prior-year published index levels. A missing current or prior value produces no derived change.
Each selected series is rebased to 100 at the first month in the visible range where every selected series has an observed level.
Each series keeps its own BLS reference base and appears in a separate panel. Cross-series index magnitudes are never overlaid.
Publisher-unavailable and unreturned slots remain null in downloads, charts, calculations, and the exact monthly ledger.
