SPECIFICATIONS OF THE SEARCH
A May 1995 search of the entire CHIRPP database (423,663 records) was conducted. The age restriction was 19 years of age or younger. Records were selected if the text fields contained the following strings "SCHOOL BUS," "AUTOBUS SCOLAIRE" or "AUTOBUS D'ECOLE." Selected records were then scanned and eliminated if the reference to a school bus was incidental to the injury. Injuries to children who had just disembarked from or were about to get on a school bus and were struck by another vehicle were included. Injuries to children waiting for a school bus were not included. The total number of records identified was 356.
OVERALL OCCURRENCE
The proportion of records in the entire CHIRPP database accounted for by injuries associated with school buses was 0.10%, with little variation from year to year.
