Research Data and Statistics on the importance of Seatbelts / Child Restraints/ Baby Seats

• A review of research on the effectiveness of seat-belts found that their use reduces the probability of being killed by 40–50% for drivers and front seat passengers and by about 25% for passengers in rear seats. 
• A study in Norway calculated that head injuries make up some 60% of all injuries to vehicle occupants. The study concluded that drivers and front seat passengers who do not use seat-belts suffer almost the same percentage of head injuries as non-users in rear seats.
• Ejection from a vehicle is one of the most injurious events that can happen to a person in a crash, with 75% of all vehicle occupants ejected from a vehicle in a crash dying as a result.
• Seat-belts are effective in preventing ejections: overall, 44% of unrestrained passenger vehicle occupants killed are ejected, partially or totally, from the vehicle, as compared to only 5% of restrained occupants.
• Seat-belts are approximately 50% effective in preventing fatalities in crashes in which motorists would otherwise die. It is estimated that seat-belt use prevented about 15 200 deaths in the United States in 2004. If all passenger vehicle occupants over 4 years of age in the United States had used seat-belts in 2004, nearly 21 000 lives could have been saved (that is, an additional 5800 lives).
• A review of various United States studies has shown that child safety seats that are correctly installed and used for children aged 0–4 years can reduce the need for hospitalization by 69%. 
• The risk of death for infants is reduced by 70%, and that for children aged 1–4 years by 47–54%. Of children aged under 5 years, 485 lives could have been saved in the United States in 2002 if all the children had been in child safety seats.
• It has been estimated in the United Kingdom that new rules on the use of child restraints rather than adult seat-belts for children up to 135 cm in height or aged 12 years and above will save over 2000 child injuries or deaths every year .
• It is estimated that within the European Union seat-belts currently reduce driver fatalities by 40%. 
• Wearing rates in European countries vary widely from around 70% to over 95%. If all European Union countries were to achieve a 99% wearing rate for drivers, 2400 lives would be saved each year.
• In many high-income countries the use of child restraints is common – with usage rates up to 90% – but in other countries they are still rarely used.
