The question of which systems would qualify as 'light rail transit systems' is debatable, so this table includes some systems (such as Toronto's) which are technically streetcars rather than 'true' light rail. 'Daily boardings per mile' figures have been rounded to the nearest 5 or 10. All figures are from 2019 and the fourth quarter (Q4) of 2019, unless otherwise noted. For Mexico, the figures are obtained from Banco de Información Económica's Instituto Nacional de Estadísitica y Geografía (INEGI), and the daily figures represent daily passenger trips averaged from the monthly and quarterly ridership figures. For light rail systems in the United States and Canada, these figures come from the American Public Transit Association (APTA) Ridership Reports statistics. Daily figures for American and Canadian light rail systems are 'average weekday unlinked passenger trips' (where transfers between lines are counted as two separate passenger 'boardings' or 'trips'), unless otherwise indicated.
