The Centers for Disease Control and Prevention divide bicyclists into several categories, reporting that two categories are at higher risks for death or injury due to accidents. The agency also reports that the majority of accidents occur in non-intersection areas of the roadway and in urban areas.
The first high-risk population of bicyclists identified by the CDC are children and young adults. This group, which ranged from 5 years of age to 24 years of age, is most likely to experience bicycle accidents that result in non-fatal injuries that are treated in hospitals. Statistically, this population accounts for around half of the emergency room reports of bicycle accidents in the country.
The next group includes a subset of the first group. Individuals aged 15 to 29 years as well as adults over the age of 45 are most likely to experience a bicycle accident with fatal injuries. The CDC did not provide comments on why these particular populations are at higher risk, though it can be assumed younger populations are less aware of others on the road and more willing to take certain risks.
The CDC says that bicycle helmets are one of the top ways of reducing risks of injury and death in a bicycle accident. Helmets can keep head injuries at a minimum, which are often the cause of death in an accident.
Other ways to stay safe on a bike include wearing more visible clothing, using reflectors and lights at night, using bike lanes and following common sense rules while on or near the road. Even when all of these measures are taken, however, accidents occur. Bicyclists who are injured in an accident caused by another's actions might have a claim for compensation to cover the expenses associated with the injury.
