32. The experts from Sweden gave two presentations (GRSP-68-08-Rev.1; GRSP-68-07), showing the results of a study whether female occupants have the same protection level as male occupants. Swedish experts also explained the issue of the lack of average female crash test dummies. She concluded that the study had shown that: (a) crash related injury risks are higher in females (especially whiplash), (b) females are poorly represented by existing crash test dummies, (c) information about body size (stature and mass) should be included in traffic injury databases and (d) injury data need to be reported for females and males separately. GRSP agreed to resume discussion on this issue at its May 2021 session.
