In Wikipedia, several road fatalities data sources were combined in order to produce the world list of traffic-related death rates: the annual number of road fatalities per capita, per vehicle fleet and per vehicle-kms. According to the World Health Organization motor vehicle collisions are the 6th most common cause of death in developed nations with an average rate of 20.8 per 100,000 populations in the year 2000 (30.8 for males, 11.0 for females). African nations have the world’s highest road traffic injury mortality rates.
