abstract="A major problem in industrial accident research is the difficulty in calculating accident rates; a difficulty caused by the unavailability of exposure data for the population at risk. In this paper it is suggested that population exposures be replaced with individual exposures (over working lifetimes) for accident victims. Besides making use only of available data, the resulting &quot;visible&quot; accident rates also make feasible a broader range of analyses. Evidence is presented to suggest that inferences made from such visible rates are similar to those that would be made from population rates (if available) as long as some control is maintained over a known source of variation, job turnover.   <p></p>",
