There are roughly 250,000 children who work on U.S. farms, that do not live on the farm, and another 30 million children who visit farms annually.[8] About every three days a child dies on a U.S. farm.[9] In 2004, most youth work fatalities occurred in the agriculture sector.[10] About two thirds of these fatalities could be attributed to transportation accidents.[10] According to the "Occupational injuries among young workers" report, most of these transportation accidents occurred either by truck or by tractor.
