The Bureau of Transportation Statistics says that Americans spent $1.4 trillion on transportation costs in 2019. According to a Bureau of Labor Statistics (BLS) Consumer Expenditure Survey for the same year, transportation is the second-highest household spending category after housing. In some parts of the country, households spend a larger portion of their income on transportation than in others. Keeping this in mind, SmartAsset crunched the numbers to identify and rank the metro areas where people are spending the highest percentage of their income on transportation costs.

We considered the average transportation spending and average household income for 22 metro areas throughout the U.S. For details on our data sources and how we put all the information together to create our final rankings, check out the Data and Methodology section below.

This is SmartAsset’s second annual study on where people are spending the most on transportation. Check out the 2019 version of the study here.

Key Findings

  • Tampa moves up. Tampa, Florida moves up one spot from No. 2 in last year’s study, moving Houston, Texas down to No. 6. The city’s transportation spending as a percentage of income increased from 13.77% during 2016-2017 to 17.00% during 2018-2019.
  • Cars cost almost 10 times more than public transportation. Across all 22 metro areas in this study, the average spent on vehicle transportation is about $10,000 (almost 11% of household income). The average spent on public transportation, meanwhile, is about $1,200 (between 1-2% of household income).

Data and Methodology

In order to find the places where people spend the most on transportation, we looked at data for 22 metro areas included in the Bureau of Labor Statistics (BLS) 2018-2019 Consumer Expenditure Survey. Specifically, we looked at data for the following metrics:

  • Average transportation spending. This is the annual amount that the average household spends on transportation (including vehicle expenses, gasoline, and public transportation). Data is from the BLS 2018-2019 Consumer Expenditure Survey.
  • Average household income. This is the annual average household income. Data is from the BLS 2018-2019 Consumer Expenditure Survey.

We divided the average transportation spending in each metro area by the average household income in that area. The result represents the average transportation spending as a percentage of total income. We ranked the places according to those percentages, from highest to lowest.
