A vehicle makes it easier for people to work and to conduct daily business such as doctor's visits and shopping. Ready access to transportation can also make it simpler to be involved in schools, religious organizations, and other forms of civic life. Vehicle access may be less critical in areas with robust public transportation.

In 2018-22, over 52,100 (14%) of households in Westchester County did not have access to a vehicle. This was lower than the state rate of 29%, higher than the national rate of 8%, and higher than the counties of Rockland (10%), Nassau (7%) and Putnam (4%). Rates in Westchester, New York State, and across the country have remained fairly steady since 2008-12. Among municipalities, the rates of households without cars were highest in Mount Vernon (33%), and Yonkers and New Rochelle (both 24%).

The multi-year figures are from the Census Bureau's American Community Survey. The bureau combined five years of responses to the survey to provide estimates for smaller geographic areas and increase the precision of its estimates. However, because the information came from a survey, the samples responding to the survey were not always large enough to produce reliable results, especially in small geographic areas. CGR has noted on data tables the estimates with relatively large margins of error. Estimates with three asterisks have the largest margins, plus or minus 50% or more of the estimate. Two asterisks mean plus or minus 35%-50%, and one asterisk means plus or minus 20%-35%. For all estimates, the confidence level is 90%, meaning there is 90% probability the true value (if the whole population were surveyed) would be within the margin of error (or confidence interval). Data for this indicator is expected to be released annually in December.
