At What Age Do Most People Break a Bone?

Studies show that fractures follow a bimodal distribution over the human lifespan, peaking in childhood and old age. While nearly half of all boys will break a bone during their youth, typically between ages 11 and 15, fracture incidence also rises significantly in older adults due to age-related bone density loss. This means the answer to the question, "At what age do most people break a bone?" is not a single number, but rather represents two distinct high-risk periods driven by different underlying causes.
