SUPPLEMENTARY INFORMATION: Aging increases a person's fragility 
(likelihood of injury given a physical insult) and frailty (chance of 
dying from a specific injury). Young adult females are more fragile 
than males of the same age, but later in life women are less frail than 
their male contemporaries. Double-pair-comparison and logistic-
regression analyses of 1975-2010 FARS, 1987-2007 MCOD, and 1988-2010 
NASS-CDS data allow quantifying the effects of aging and gender on 
fatality and injury risk and studying how trends have changed as 
vehicle-safety technologies developed.
    In crashes of cars and LTVs of the past 50 model years, fatality 
risk increases as occupants age, given similar physical insults, by an 
average of 3.11  .08 percent per year that they age. 
Fatality risk is, on average, 17.0  1.5 percent higher for 
a female than for a male of the same age (but more so for young adults 
and much less so for elderly occupants). The relative risk increases 
for aging and females may have both intensified slightly from vehicles 
of the 1960s up to about 1990 (even while safety improvements greatly 
reduced the absolute risk for men and women of all age groups); since 
then, the added risk for females has substantially diminished, probably 
to less than half, while the increase for aging may also have 
diminished, but by a much smaller amount. AIS >= 2 nonfatal-injury risk 
increases only by 1.58  .35 percent per year of aging, but 
it is 28.8  6.0 percent higher for a female than for a 
male.
    Older occupants are susceptible to thoracic injuries, especially 
multiple rib fractures. Females are susceptible to neck and abdominal 
injuries and, at lower severity levels, highly susceptible to arm and 
leg fractures. Female drivers are especially vulnerable to leg 
fractures from toe-pan intrusion. All of the major occupant protection 
technologies in vehicles of recent model years have at least some 
benefit for adults of all age groups and of either gender; none of them 
are harmful for a particular age group or gender. Nevertheless, seat 
belts have been historically somewhat less effective for older 
occupants and female passengers, but more effective for female drivers. 
Frontal air bags are about equally effective across all ages; side air 
bags may be even more effective for older occupants than for young 
adults. Air bags and other non-belt protection technologies are helping 
females just as much and quite possibly even more than they protect 
males; this may have contributed to shrinking the historical risk 
increase for females relative to males of the same age.

Procedural Matters

How can I influence NHTSA's thinking on this subject?

    NHTSA welcomes public review of the technical report. NHTSA will 
submit to the Docket a response to the comments and, if appropriate, 
will supplement or revise the report.

How do I prepare and submit comments?

    Your comments must be written and in English. To ensure that your 
comments are correctly filed in the Docket, please include the Docket
