Average trip length among U.S. children

This bar graph sample shows the average trip length (in miles) among U.S. children aged five to 15 years. It was designed on the base of the figure 3 from the article "Childhood Obesity — What We Can Learn From Existing Data on Societal Trends, Part 2" on the U.S. Centers for Disease Control and Prevention (CDC) website.
"Active transportation, such as walking or biking, can expend a large amount of energy, and it has been hypothesized that increased suburbanization reduces walking and biking. Only recently have transportation patterns and urban design in relation to physical activity and health attracted interest. Although research has been limited to cross-sectional comparisons and adults, it has shown an association between increases in sprawl and decreases in leisure time and utilitarian walking and increases in body mass index and chronic health conditions."
