Vehicle access describes households

The no-vehicle indicator divides households reporting no available vehicle by occupied households. It does not count only commuters and does not say how many individual residents lack access to a car. Some households include several people or no employed members. Availability is the source concept; it is not identical to ownership or the number of registered vehicles in a state.

Commuting describes workers and a usual work trip

Public-transit and drive-alone shares use workers age 16 and older. They describe the source-defined usual means of getting to work, not every trip a resident makes. Shopping, school, healthcare and leisure travel are outside this commuting question. Transit commute shares are also different from transit system ridership totals: operational trips can include repeated journeys by the same person.

The state average hides local variation

New York’s statewide figure combines communities with very different transport networks and land-use patterns. It is not a proxy for every county or New York City neighborhood. For a county question, inspect the corresponding county estimate and source period. A local transit operator’s service area may cross county boundaries and requires another geographic definition.
