What age group of bicyclists is most likely to have fatalities based on the chapter's findings?

The age group of 45-64 is identified as having the highest likelihood of fatalities among bicyclists based on the chapter's findings. This demographic can often be involved in situations that lead to serious accidents due to factors such as decreasing reaction time, potential health issues that may not be as prevalent in younger age groups, and possibly less experience riding bikes compared to younger riders who might be more active in cycling.

Additionally, individuals in this age range might also be participants in a greater variety of cycling activities, which can expose them to higher-risk environments, such as busy roadways or urban settings, where accidents are more likely to happen. These contributing factors establish a clearer understanding of why this particular age group shows a higher statistical incidence of fatal outcomes compared to other younger age brackets, which may have more robust physical capabilities and be engaged in cycling more recreationally.
