Driven to Spend: 
How Sprawl and the Lack of Transportation Choice 
Are Driving Up Family Transportation Costs

by Roy Kienitz
STPP Executive Director

Transportation is a big expense for America’s families. Our newest study, Driven To Spend, conducted with the Center for Neighborhood Technology, looks at the effect of our transportation system on family finances.   This report is a departure from our previous work.  In the past, STPP has focused on the costs and benefits of different forms of transportation spending by government.  But this isn’t the whole picture.  Individuals spend five times as much of their own money on transportation as governments spend on their behalf.  What about this spending?

Several months ago we set out to understand how much people are spending, what they’re spending it on, and why.  It turns out that American families spend a lot on transportation: nearly 19 percent of the average family budget in 1997 and 1998.  And this varies widely from place to place.  In some metro areas, more than 22 percent of household spending goes for transportation; in others, only 15 percent.  Understanding this variation was the primary goal of our research.

In our analysis, two factors emerged as correlating strongly with the variation in family transportation costs: access to multiple forms of transportation, and sprawl.  This pattern is found at many different levels.  In particular, access to a variety of transportation choices is associated with lower costs when comparing different neighborhoods within a metro area, when comparing different U.S. metro areas to one another, and when comparing metro areas in the U.S. to their counterparts in Canada, Europe, Australia and Asia.  And the difference can be thousands of dollars per year.

Our most troubling findings relate to the predicament of those trying to work their way out of poverty.  Transportation costs eat up a staggering 36 percent of the average income of households in the bottom income quintile, those earning less than $12,000 per year.  And this spending does little to generate equity over time.  Freeing up a portion of these resources to invest in home ownership would give low income families a better chance of  moving into the middle class.  Over the course of a decade, $30,000 invested in owning, using and maintaining a car can be expected to result in just $3,000 in equity.  The same $30,000 invested in owning and maintaining a house on average yields more than $13,000 in equity. 

For too many poor families, the need to own one or more cars is placing out of reach the single most effective tool for accumulating family wealth over time: owning a home.  We realize that transportation policy makers are not used to thinking in these terms.  Driven To Spend makes the case that it’s time to start.
