Mass transit ridership has declined over the past decade as increasing numbers of people are choosing to drive private vehicles.

While Southern California added 2.3 million people from 2000 to 2015, it added and 2.1 million vehicles, or an average of 0.95 vehicles per new resident. This is a significant change change from 1990 to 2000, when the region added 1.8 million people but just 456,000 vehicles, the equivalent of 0.25 vehicles per new resident.
