New Report Shows Mounting Evidence of Millennials’ Shift Away from Driving

The 2000s saw a marked decrease in the average number of miles traveled by young Americans, and that trend appears likely to continue even as the economy improves, due to the consistency of Millennials’ surveyed preferences, a continued reduction of Millennials driving to work, and the continued decreases in per-capita driving among all Americans.

Millennials in Motion

Millennials are less car-focused than older Americans and previous generations of young people, and their transportation behaviors continue to change in ways that reduce driving. Now is the time for the nation’s transportation policies to acknowledge, accommodate and support Millennials’ demands for a greater array of transportation choices.

New Study: Traffic Data Does Not Support Spending on "Opportunity Corridor"

A new report by Ohio PIRG Education Fund names the "Opportunity Corridor" one of 11 examples of wasteful highway spending, based on its outdated assumptions of ever-increasing driving. The study, which details ten other highway “boondoggles” across the country, points out that the community has called for other transportation priorities, and that the data shows driving in the area has been on the decline for ten years. The study calls for the state to consider reprioritizing scarce transportation dollars to other projects.

Highway Boondoggles

Even though the Driving Boom is now over, state and federal governments continue to pour vast sums of money into the construction of new highways and expansion of old ones – at the expense of urgent needs such as road and bridge repairs, improvements in public transportation and other transportation priorities. Eleven proposed highway projects across the country – slated to cost at least $13 billion – exemplify the need for a fresh approach to transportation spending.

A New Course

Universities and colleges across the country are taking steps to encourage their communities, students, faculty and staff to decrease their reliance on personal vehicles. These efforts are working well – saving money for universities, improving the quality of life in college towns, and giving today’s students experience in living life without depending on a personal car.

A New Way to Go

America is in the midst of a technological revolution … and a big shift in our transportation habits.

Over the last 15 years, the Internet and mobile communications technologies have transformed the way Americans live and work. During that same period, growth in vehicle travel slowed and then stopped, with Americans today driving about as much on average as we did in 1996.

Both changes have taken place most rapidly among young Americans, who have been the earliest and most enthusiastic adopters of new technologies, as well as the new social networking tools that are the foundation of the emerging “sharing economy.” They have also been the group that has reduced its driving the most, with the average American between 16 and 34 years of age driving a startling 23 percent less in 2009 than in 2001.

Could these developments – the rapid spread of mobile, Internet-connected technologies, the emergence of social networking, and the recent decline in driving – be related? And what does the future hold?

Early evidence suggests that new innovations in technology and social networking are beginning to change America’s transportation landscape. New transportation services are providing people with an abundance of new options, helping to overcome barriers to the use of non-driving forms of transportation, and shifting the economics behind individuals’ travel choices. Collectively, they are also opening up the opportunity for more Americans to adopt “car-free” and “car-light” lifestyles with dramatically less driving.

America is in the midst of a technological revolution.

  • Between 2000 and 2012, the percentage of adults who use the Internet increased from 46 percent to 82 percent. The percentage of adults who own a cell phone increased from 53 percent to 88 percent. The share of Americans with access to high-speed Internet at home increased from 5 percent to more than 70 percent. And roughly half of Americans now own smartphones, which did not exist in their modern form in 2000.
  • These technologies are changing how Americans live and work. Participation in telework and e-commerce has increased dramatically in the last decade. Meanwhile, social networking has helped unleash an emerging “sharing economy” that provides more people with convenient access to mobility that had once been available only to those who owned a car.
  • Young Americans have consistently been the first to adopt and test the capabilities of these new technologies and practices. As of September 2012, young adults were six times more likely to have a smartphone than people in their grandparents’ generation, and twice as likely as those between 50 and 64 years of age.

Advances in the Internet and mobile communications technologies have unleashed a wave of new technology-enabled transportation services.

  • Carsharing Classic roundtrip carsharing services, such as Zipcar and City Carshare – as well as newer one-way services such as car2go – enable subscribers to access cars located in their neighborhoods and on their college campuses, providing participants with the mobility benefits of access to a car without having to bear the burden of owning one. As 2012, more than 800,000 Americans were members of carsharing services (sharing a combined fleet of more than 12,000 vehicles). Newer peer-to-peer carsharing networks enable individuals to rent out their own unused vehicles to people looking for a car.
  • Bikesharing – Six years after the launch of the first modern bikesharing system in the U.S., more than 30 cities now have programs where subscribers can access bikes by the minute or by subscription at kiosks located on city streets. In just its first season, New York City’s Citibike program enlisted more than 70,000 annual members, with riders traveling more than 4.5 million miles.
  • Real-time transportation information The majority of U.S. transit systems now make scheduling information publicly available, enabling developers to produce a variety of new smartphone apps to help riders navigate urban transportation systems. Smartphone-based tools enable riders to find the best route for their trip, track the progress of trains and buses in real time, and even, in some cases, pay their fare.
  • Ridesharing – A variety of new services across the country pair ordinary people with open seats in their cars with individuals who need a ride. Using the Internet and smartphones to facilitate rides enables those seeking shared rides to tap a broader pool of potential matches.
  • Taxi and transportation network services – New services enable people to hail taxis or livery vehicles, or to arrange rides with ordinary drivers (e.g., Lyft and Sidecar) via smartphone, making it easier, and often less expensive, to hire a ride.
  • Multi-modal tools – New apps and tools also enable individuals to plan trips using several modes of transportation, facilitating efficient, seamless, door-to-door trips.

Technology-enabled transportation services have the potential to change Americans’ transportation behaviors.

  • Technology-enabled services can eliminate traditional barriers that prevent Americans from taking public transit or sharing rides and vehicles.
  • The array of new services can make it easier for households to reduce the number of vehicles they own – a step that generally leads to steep reductions in driving.
  • Technology-enabled services can expand the availability of transportation choices in places and markets where they are not currently available.
  • Access to mobile technology also enables riders to use their time riding on trains or waiting for buses more productively. This provides shared transportation with a market advantage over driving, since the use of mobile technology is increasingly understood as being incompatible with the safe operation of a car.

While many of these new tools are in their infancy, several have already been shown to reduce vehicle ownership and driving.

  • Each carsharing vehicle replaces nine to 13 privately-owned vehicles, and the average carsharing participant reduces his or her driving by 27 to 56 percent. About 25 percent of carsharing participants sell a vehicle after joining while another 25 percent forgo vehicle purchases they otherwise would have made.
  • A study of the Chicago transit system, which gradually introduced a real-time bus location information system from 2006 to 2009, found that introducing real-time information increased weekday bus ridership.
  • Approximately 40 percent of bikeshare members report reducing their driving, according to a 2011-2012 survey of members of four North American bikeshare services. A 2013 survey of members of Washington, D.C.’s Capital Bikeshare program found that one quarter reported having reduced the number of miles they drove since joining the service. Five percent of members reported having sold a personal vehicle since joining the service, with 81 percent of those members reporting that joining Capital Bikeshare was a factor in the decision. The total reduction in vehicle travel by Capital Bikeshare members was estimated at 4.4 million miles.

The cumulative impact of new transportation services on vehicle ownership likely exceeds that of the individual services.

  • By providing more choices and flexibility for individuals to meet their transportation needs, these new tools can make it convenient to adopt “car-free” and “car-light” lifestyles that dramatically reduce driving.
  • Households that reduce the number of vehicles they own often dramatically reduce the number of miles they drive. Because many of the costs of owning a car are perceived to be fixed, vehicle owners perceive the cost of driving an additional mile to be artificially low. New services such as carsharing shift the cost of driving from fixed to per-mile costs, providing an incentive for users to drive less.
  • Information technologies make it easier to ensure seamless connections between various modes of transportation, expanding the number and types of trips that can be completed effectively without a car.

Cities, states and the federal government should take a series of immediate steps to unlock the potential of technology-enabled transportation services to provide Americans with more and better transportation choices, while integrating new technologies into transportation planning and policy. Specifically, governments should:

  • Use information technology to facilitate the development of technology-enabled services by providing open access to transit scheduling and operations data, providing real-time transit information at stations, bus stops and elsewhere, ensuring wi-fi and/or cellular network access on all transit vehicles, and creating multi-modal connections with emerging transportation services.
  • Modernize regulations to accommodate carsharing, bikesharing, ridesharing, and other transportation services in ways that unlock the tremendous potential of these services while ensuring strong protection for consumers and residents.
  • Embrace a multi-modal future – Transportation planners should seek to integrate new technology-enabled services and existing transportation services into integrated systems that provide efficient, seamless, door-to-door connections. Officials should incorporate new transportation tools into all aspects of transportation planning and decision-making, while breaking down outdated mode-specific “silos” in transportation agencies and financing. Governments should make strategic investments in tools to integrate and maximize the benefits of new transportation innovations, while also investing in the basic infrastructure – such as transit lines and improved facilities for bicycles and pedestrians – that provides individuals with high-quality transportation choices.
  • Extend the use of technology-enabled tools to new communities – Local and state governments should expand access to technology-enabled services to areas beyond the major cities in which they have taken root, surmount economic and other barriers to the use of those alternatives, and explore the potential uses of Internet and mobile communications technologies in expanding access to high-quality public transportation in areas that currently do not have the population density to sustain such service.
  • Learn and adapt by tapping the rich information offered by new technologies to improve the quality of transportation services. Local, state and federal officials should also invest in research to explore the impact of recent technological changes on future expectations of demand for driving.


Public officials should also ensure that plans for future transit and road capacity investments adequately reflect the emergence and potential of new technology-enabled tools to reduce driving. Governments should cancel plans for highway expansion projects that no longer make sense amid recent trends toward reduced driving and the emergence of new technologies.

Moving Off the Road

After sixty years of almost constant increases in the annual number of miles Americans drive, since 2004 Americans have decreased their driving per-capita for eight years in a row. Driving miles per person are down especially sharply among Millennials, America’s largest generation that will increasingly dominate national transportation trends. But some skeptics have suggested that the apparent end of the Driving Boom might be just a temporary hiccup in the trend toward more driving for Americans. By the time Americans took notice of the decline in driving, the economy was in deep recession. Would economic growth bring back rapid increases in driving? Doubts about whether the Driving Boom has ended make it easier to postpone choices about transforming our transportation system or enacting reforms that disrupt well-established interest groups.


This report for the first time presents government data on state-by-state driving trends. It analyzes which states drive more miles per-person, which states have reduced their driving the most since the end of the national Driving Boom, and how state changes in driving behavior correspond to other changes such as growing unemployment or urbanization.

Forty-six states plus the District of Columbia witnessed a reduction in the average number of driving miles per person since the end of the national Driving Boom. North Dakota, Nevada, Louisiana and Alabama are the only states in the nation where driving miles per capita in 2011 were above their 2004 or 2005 peaks. Meanwhile, since 2005, double-digit percent reductions occurred in a diverse collection of states: Alaska, Delaware, Oregon, Georgia, Wyoming, South Carolina, the District of Columbia, Pennsylvania, Indiana and Florida.

The fifty states plus the District of Columbia offer a useful natural experiment to examine different factors behind America’s reduction in driving since 2004. Examining the commonalities and differences in driving trends among states can provide insight into the potential causes behind the downturn in driving and the direction of future trends.


This study finds that declining rates of driving do not correspond with how badly states suffered economically in recent years. On the contrary:

• Among the 23 states in which driving miles per person declined faster than the national average, only six saw unemployment increase faster than the nation as a whole.

• Among the 10 states with the largest declines in driving per person, only two rank among the ten with largest increases in unemployment.

• Among the 23 states where driving declined faster than the national average, only 11 saw faster-than-average declines in the employed share of their working-age population.

• Among the 10 states with the greatest reductions in the employed share of population, only two were also among the ten states with the largest reductions of driving (Georgia and the District of Columbia).


The evidence suggests that the nation’s per capita decline in driving cannot be dismissed as a temporary side effect of the recession. While certainly a contributing factor and an economic rebound could be expected to have some upward lift on driving, the recession does not appear to be the prime cause of the fall off in driving over the past eight years. Nor is it clear that future economic growth would lead to a resumption of the postwar Driving Boom. Policy makers can stop wondering whether American driving trends are changing. They should focus carefully on these trends, and start adapting policies to match them.

New Report: Reduction in Driving Likely to Continue

COLUMBUS ­­—As the average number of miles driven by Americans heads into its eighth year of decline, a new report from the Ohio PIRG Education Fund finds that the slowdown in driving is likely to continue. Baby Boomers are moving out of the phase in their life when they do the most commuting, while driving-averse Millennials move into that phase. These demographic changes will likely keep driving down for decades, according to the report, “A New Direction: Our Changing Relationship with Driving and the Implications for America’s Future.”
