What is Road accident involvement per miles travelled—IV about?

## Age of driver Fig. I. Age of driver. Vehicle-miles of population performance (I), accident involvements (2). and involvement rates per lo\* miles of exposure (3). as ratios of the average performance, average involvement, and the annual over-all involvement rate respectively: Queensland. 1%1. rate rank follows exactly the increasing age rank up to age 60. But beyond this the involvement rate of the 60 and over age group is of statistically the same magnitude as that of the 50-59 age group. Many earlier studies have shown a rate increase for the over 60 age group when compared with the rate of the age group immediately below it. It may be that if the oldest sector of these drivers (say above 70) were shown separately, an increase would appear. This refinement was not possible here because of small sample-size. Nevertheless this may be the first study of its kind where large sample records of actual mileage of a whole driver population were used in calculating the denominator, and a whole year of accident occurrences for the numerator. It may be that this refinement, if compared with earlier methods using estimates of annual total mileage performances, petrol consumption, etc. can
