Figure 2 data,
when compared among age groups—indicates fatalities
among the 51-55 age group have increased an annual average
of 5.2 percent per year (the highest among all age groups).
The 56-60 and 46-50 age groups have the secondhighest
and the third-highest increases in fatalities per year.
This is most likely due to high stress levels, fatigue
and an increase in the population of this age group.
