In order to permit meaningful comparisons of the statistics, for example between different periods, economic activities, regions and countries, account needs to be taken of the differences in employment size, changes in the number of workers in the reference group, as well as in the hours worked by those in the reference group. A number of rates which take into account these differences may be calculated, including the following measures, which are among those most useful for comparing information at both the national and international levels. The term “workers in the reference group” refers to those workers in the particular group under consideration and covered by the source of the statistics of occupational injuries (for example those of a specific sex or in a specific economic activity, occupation, region, age group, or any combination of these, or those covered by a particular insurance scheme). ... ... @@ -130,30 +130,27 @@ 130 130 131 131 For each of the measures below, the numerator and the denominator should have the same coverage.
