2016 data. There's a chart breaking down the income levels and types of travel.. . . Driving alone is most likely (at 81.4%) for those earning between $50,0000 and $64,999, and this percentage decreases as earnings decrease or increase. Driving alone is least likely (at 66.1%) for those earning the least.
Carpooling is most likely (at 12.5%) for those earning the least, and this percentage decreases as earnings increase. Carpooling is least likely (at 5.8%) for those earning the most.
Using public transportation is least likely (at 3.9%) for those earning between $35,000 and $49,999, and this percentage increases as earnings decrease or increase. Using public transportation is most likely (at 6.6%) for those earning the most.
Walking is least likely (at 1.4%) for those earning between $65,000 and $74,999, and this percentage increases as earnings decrease or increase. Walking is most likely (at 6.5%) for those earning the least.
Working from home is least likely (at 3.7%) for those earning between $25,000 and $49,999, and this percentage increases as earnings decrease or increase. Working from home is most likely (at 7.5%) for those earning the most.
In comparison to those earning the most, those earning the least are about 1.2 times less likely to drive alone, use public transportation, and work from home, but 2.2 times more likely to carpool and 3.6 time more likely to walk.
How much the obtained patterns reflect necessity versus choice cannot be ascertained from these data. However, those who earn more generally have more choices available.
