How Demo City moves: a look at public transit patterns

This story draws on 2,000 days of daily ridership data — from June 2020 through November 2025. Beneath the headline numbers, the data reveals a city whose transit pulse follows the school calendar, the workweek, and the holidays with striking regularity.

The weekly pulse

Averaged across all weekdays in the dataset (June 2020–November 2025), Demo City's transit system carries roughly 796,000 riders per day. On Saturdays that figure falls to 565,000. On Sundays and public holidays, it drops further still — to 423,000, barely half a weekday.

The gap is not subtle. It tells you something direct about who the system is built for: the commuter, moving Monday through Friday, anchors the network. Weekend ridership, while substantial, represents a fundamentally different kind of trip.

The seasonal beat

The weekly pattern repeats itself at the scale of the year — but the shape is not what most people expect. Ridership does not peak in summer. It peaks in autumn.

Monthly averages pooled across the full period (June 2020–November 2025) show ridership climbing steadily from January (576,000 daily riders) through spring, before dipping in June and July (714,000 and 698,000 respectively) as school lets out and commuter patterns shift. Then September arrives. Ridership surges back to 782,000 — its highest point of the year — and holds there through October.

December is the sharpest drop: 595,000 average daily riders, as the holiday period hollows out the commuter base.

The city goes quiet

Every year, one day stands apart. Christmas Day consistently produces the lowest ridership of any day in the dataset.

In 2020, the floor was 121,644 — a figure shaped in part by the pandemic, but striking nonetheless. In 2022 it dipped again to 140,554. By 2024, Christmas ridership had risen to 232,879 — a sign of the city's recovery, but still roughly half a typical Sunday.

The chart below shows Christmas Day ridership for every year in the dataset. The trend is uneven but broadly upward: even the quietest day of the year has gotten busier.

Bus and rail

Over the full period (June 2020–November 2025), 59% of all boardings were on bus and 41% on rail — a split that has held broadly consistent throughout. The two networks follow the same rhythm: the weekly pulse, the seasonal beat, the holiday valley. They are different in geography and infrastructure, but they breathe together.
