Methodology and Sources
=======================

Metric definition:
Standard adult public transport monthly pass price converted to USD equivalent (USD equivalent per month or closest 30/31-day adult pass).

Ranking logic:
Higher values rank higher.

Methodology extracted from article:
Methodology The metric is the price of a standard adult monthly, 30-day or 31-day public transport pass, expressed as a U.S. dollar equivalent. The ranking direction is descending because the article ranks cities by higher nominal pass price first. The target year is 2026, using official fare pages available for the 2026 fare year or current 2026 fare snapshot. The source hierarchy is official transport authority first, then official fare shop or fare authority, then government transport information. Commercial cost-of-living datasets were not used as row sources. Currency conversion uses the European Central Bank reference exchange-rate snapshot for 4 June 2026. For currencies quoted by the ECB as local currency per euro, the formula is: USD equivalent = local fare ÷ ECB local-currency-per-euro rate × ECB USD-per-euro rate. For euro fares, the formula is: USD equivalent = euro fare × 1.1640. For U.S. dollar fares, the value is unchanged. Inclusion rule A row is included only when a public adult monthly, 30-day or 31-day fare product is visible from an official source and the product is usable for ordinary urban travel rather than a special discount group. Exclusion rule Student, youth, senior, disabled, employer-subsidized, tourist-only, airport-only, annual-only and fare-capped daily products are excluded unless the source identifies them as the standard monthly adult product. Official value status Each row is marked official_value because the local fare base is an official published tariff. The USD number is a calculated equivalent used only for cross-city comparison, not an official USD tariff and not a growth projection. Rounding and limits USD equivalent values are rounded to two decimals. The ranking does not normalize by income, service area, number of zones, network quality, fare caps, tax funding, employer subsidies or purchasing power. Missing values are not imputed. If a city has several monthly products, the table uses the most central standard adult monthly product that can be clearly tied to the city or metropolitan travel zone. Conflicting values are not averaged; official current fare pages take priority over media reports and secondary aggregators. Toronto is retained because the adult monthly pass is still part of the 4 June 2026 snapshot, but the table note flags the scheduled discontinuation after 31 August 2026.
