A need to better understand the multidimensional nature of disadvantage is leading to the adoption of a wider range of measurement variables. One variable now commonly adopted is zero car ownership. This paper challenges the logic of including "not having a car" as an indicator of disadvantage. It argues that this can distort the real picture of disadvantage. It presents evidence to show that zero car ownership can be a positive feature of low income households and that conversely high car ownership can put significant financial stress on households with low income.
