Figures are from the Federal Transit Administration's National Transit Database (NTD) annual reporting for 2024, the most recent published report year. Cost per rider is operating expense divided by unlinked passenger trips. Farebox recovery is fare revenue divided by operating expense. Ten-year trends are adjusted for inflation to 2024 dollars; single-year figures are as reported. Agencies self-report to the NTD, and reporting practice varies, so figures are best read as comparable in magnitude rather than to the cent.
