Ridership Statistics

CTA Ridership
CTA bus and rail ridership results are all collected using the farebox. Each customer boarding a bus or passing through a rail station turnstile is counted as a single rider.
Metra Ridership
Metra Rail Summary data is an estimate based on ticket sales (monthly, 10-ride and one way) for a given month. The data is by line and branch and is a combined total for weekday, Saturday and Sunday/holiday.

Metra Station Detail data is based on a count of boardings (the number of passengers boarding a train) and alightings (the number of passengers exiting a train) on a given weekday for each station and for each train.
Pace Ridership
Pace ridership results are primarily collected using the electronic fare collection systems for each passenger boarding a bus. Ridership for Pace's contract bus routes, which do not have electronic fare collections systems, is manually reported. Both datasets are reporting in the RTAMS.
RTA Ridership
The RTA's annual unlinked passenger trips include CTA bus, CTA rail, Metra rail, Pace bus, CTA and Pace paratransit, Pace dial-a-ride, and Pace vanpool services.
NICTD Ridership
NICTD Rail Summary data is an estimate based on ticket sales (monthly, 10-ride and one way) for a given month. The data is by line and branch and is a combined total for weekday, Saturday and Sunday/holiday.

NICTD Station Detail data is based on a count of boardings (the number of passengers boarding a train) and alightings (the number of passengers exiting a train) on a given weekday for each station and for each train.
