About the data

These aren’t ridership figures — only transit agencies themselves can give official ridership stats. But we can use the frequency of Transit app opens as a rough proxy for demand across our supported cities.

We compare actual usage of the app, to projected use of the app based on last year’s numbers (adjusted for annual growth) to measure how far we are from “normal.” You can compare these numbers across different cities and agencies.
