High Quality Content by WIKIPEDIA articles! Worldwide it was estimated that 1.2 million people were killed and 50 million more were injured in motor vehicle collisions in 2004. This makes motor vehicle collisions the leading cause of death among children 10 – 19 years of age (260,000 children die a year, 10 million are injured) and the sixth leading preventable cause of death in the United States (45,800 people died and 2.4 million were injured in 2005). Modern accident statistics often focus on reportable injury accidents (which include deaths) rather than reporting on deaths alone. It is believed that serious accidents are often significantly under-reported, under-recorded and misclassified and that the completeness of reporting may vary over time and between sources.
