Did You Know?
Since everyone walks, it’s easy to take for granted. And that’s exactly what the transportation planning profession has done — with rather unfortunate results. Consider:
- Walking is by far the most popular form of physical activity in the United States.
- Although 41% of all trips made in the United States are one mile or less, fewer than 10% of all trips are made by walking and biking. 
- Among students living within 1 mile of school, the percentage of walkers fell from 90% to 31% between 1969 and 2001. 
- According to the CDC, only 13% of children walk to school today compared with 66% in 1970.
- Parents driving children to school comprise 20-30% of morning traffic congestion in urban areas.
- Children on a walking school bus walk at about 2 miles per hour, which is half the rate of a typical young adult. The average person takes 2,000 steps per mile.
- 10,000 steps per day – about 5 miles – is a great way to walk your way to fitness.
- According to the CDC , 33% of U.S. adults are classified as obese (BMI≥30), compared to 15% in the 1970s.
- Brisk walking (≥3.5 mph) has been shown to reduce body fat, lower blood pressure, increase high-density lipoprotein, and even reduce risks of bone fracture.
- Brisk walking has also been associated with lower mortality rates from cardiovascular disease and cancer.⁴
- 21% to 34% of U.S. adults meet public health recommendations (5 times per week for at least 30 minutes) for physical activity by walking. 
- In the last 40 years, childhood obesity has increased 5-fold for kids age 6-11.
- Providing ideal conditions for walking is illegal in most suburban communities.
- Each year 6,000 pedestrians are killed and 90,000 are injured. One in five is a child.
- You are 36 times more likely to be killed walking than driving a car.
- You are 300 times more likely to be killed walking than flying.
- Less than 6% of Americans’ trips are on foot, yet 13% of all traffic deaths involve pedestrians.
- For every pedestrian killed by a car, at least 14 more are injured.
- Almost 60% of pedestrian deaths occur in places where no crosswalk is available.
- Being hit and killed by a car is now the second leading cause of fatal injury and the fourth leading cause of hospitalized injury for California children aged 5-12.
- Pedestrian fatalities have declined steadily over the last 20 years, mainly because US residents increasingly live in suburbs, where residents walk far less.
- In a San Francisco study, average medical costs for treating pedestrian crashes during 2004-2008 was $47,303-$77,679 per patient for admitted patients and $3,798-$6,405 for non-admitted patients. The highest cost for a single patient was $1.9 million. The highest cost directly billed to an uninsured patient during this period was $505,952. 
- According to 2004 data from AAA estimates and US Census surveys, ownership costs of one motor vehicle — $7,834 for a sedan (AAA, Your Driving Costs) — accounts for more than 18 percent of a typical household’s income.
- Because of the health benefits, the cost of walking is actually negative. 
- The cost of single traffic fatality is $3.36 million in Year 2000 dollars.
