A nationally representative study found that fall-related fractures (e.g., broken fingers and wrists) decreased slowly and steadily, among boys and girls, from 2001 to 2015, but there was one group that stood out—boys ages 10–14 showed a sharp drop after 2009. This suggests a sharp drop in doing things that could lead to a fall, such as riding bicycles over jump ramps, or climbing trees.[30]
