Is Uber causing car ownership to fall?

Car Ownership in by State

Hard to say with certainty. Car ownership is associated with a number of things, among them income and age. Utah has the largest Millenial population of all the states, and younger people tend to have lower incomes. Similarly, Utah has experienced housing price increases far beyond that supported by local wages (thanks California), making home ownership less affordable. Hypothetically, Millenials may be compensating by purchasing townhomes and condos (with limited parking) or by foregoing cars.
