Helmet Use Among U.S. Motorcyclists Who Died in Crashes 2008–2010
This is an interesting and quite detailed study regarding the use of motorcycle helmets. It would be interesting to see how much of this data is transmutable to bicycle helmet use or non use and related injuries. The CDC (Centers for Disease Control; cdc.gov) analysed fatal crash data from 2008 to 2010, where a total of 14,283 motorcyclists were killed in crashes, among whom 6,057 (42 percent) were not wearing a helmet. In the 20 states with a universal helmet law (like California), 739 (12 percent) fatally injured motorcyclists were not wearing a helmet, compared with 4,814 motorcyclists (64 percent) in the 27 states with partial helmet laws and 504 (79 percent) motorcyclists in the three states without a helmet law. As of April 2012, 19 states and the District of Columbia had universal helmet laws, 28 states had partial helmet laws, and three states had no helmet law. The full report is available here in pdf
