Families bereaved by road traffic crashes: linkage of mortality records with 1971-2001 censuses.

In a sample of approximately 1.1% of the population in 1971-2005, a total of 1801 adults and children died in road traffic crashes. These deaths left 6467 close family members bereaved in 2005, corresponding to a total of 590 518 bereaved in the population (including 131 399 parents who had lost a child and 107 384 offspring who had lost a parent). Over 1% of the population of England & Wales alive in 2005 had lost a close family member in a fatal road traffic crash since 1971. This may imply a greater public health burden of road traffic crashes than_previously estimated.
