The Centers for Disease Control and Prevention (CDC) has come up with a report on child passenger safety. One of the best news in the report is a decline of 43% has been witnessed in the number of US children dying in car crashes from 2002 to 2011.

But the saddest part of the report is more than 9,000 children have lost their lives in car crashes. The study has found one in three of the children who had died in car crashes in 2011 were not wearing seat belt. The CDC said that it is an important revelation as more number of deaths could have been prevented with the use of easy safety measure.

CDC Director Thomas Frieden has warned that thousands of children are at risk as they are not wearing seat belts. Majority of black and Hispanic children who have died in 2009 and 2010 were not buckled in comparison to white children.

For now, it has not been unveiled as why racial difference prevailed in the usage of seat belts. It is suspected that socio-economic factors might be having a role to play. The researchers have analyzed the data collected from the National Highway Traffic Safety Administration.

CDC researchers have assessed the data of all the deaths taken place of children in cars from 2002 to 2011. Some of the other things revealed by report are a rise in the seat belt usage among children. From 88% in 2002 to 91% in 2011 has been found among children age 7 and under. Older children were having fewer chances to wear seat belts in comparison to younger children.
