Can you tell me statistics on the rate of accidents caused by elderly drivers, compared to other age groups?

Studies have found that elderly drivers are involved in fewer fatal crashes on a per-mile driven basis than younger drivers, but their involvement in crashes increases as a percentage of total registered drivers. Data from the National Highway Traffic Safety Administration shows that older drivers are involved in approximately 5.6% of all fatal crashes while they comprise just 8.5% of total drivers. In contrast, teen drivers are involved in 14.4% of fatal crashes while they represent 14.3% of total drivers. Additionally, among drivers ages 70 and older, the fatal crash involvement rate was lower than younger drivers in every size group except for the 66 to 70 age group, where it was higher.
