Furthermore, the proportion of reporting households is significant across all income quintiles. There is, however, an important difference for households in the middle and highest income quintiles, compared to those in the lowest: while some report spending on city/commuter transportation modes, practically all of the people in these higher quintiles report expenditures on operating a personal vehicle (see Figure 9.11 ).
Si l'on prend les ménages qui faisaient état de telles dépenses en 2002, les dépenses moyennes atteignaient 348 $ pour le quintile du plus faible revenu et 523 $ pour le quintile du revenu le plus élevé.
