Abstract
The National Crash Severity Study (NCSS) data file was interrogated to determine whether occupants of different statures and masses are subject to different injury severity rates. The NCSS data was divided into four height and weight categories. Injury severity rates were calculated for each category. The data was also interrogated for occupant size effects relative to frontal and side impacts, male and female occupants, use or non-use of restraints, and driver and right occupant positions.
