Later revisions are indexed and available in hard-copy versions. The WHO does not permit simultaneous classification in two separate areas.

Each year the report combines an expert assessment of global health, including statistics relating to all countries, with a focus on a specific subject.

Global plan of action on workers' health is a draft to protect and promote health in the workplace, to improve the performance of and access to occupational health services, and to incorporate workers' health into other policies. The WHO has emphasized the effort because, despite the availability of effective interventions to prevent occupational hazards, large gaps exist between and within countries with regard to the health status of workers and their exposure to occupational risks. According to the WHO, only a small minority of the global workforce has access to occupational health services. The action plan deals with aspects of workers' health, including primary prevention of occupational hazards, protection and promotion of health at work, employment conditions, and a better response from health systems to workers' health.

According to The WHO Programme on Health Statistics:

The production and dissemination of health statistics for health action at country, regional and global levels is a core WHO activity mandated to WHO by its Member States in its Constitution. WHO produced figures carry great weight in national and international resource allocation, policy making and programming, based on its reputation as "unbiased" (impartial and fair), global (not belonging to any camp), and technically competent (consulting leading research and policy institutions and individuals).
