What O includes

• This major section encompasses activities typically carried out under government administration, such as legislation, legal interpretation, law enforcement, and the administration of laws. It includes legislative activities, tax collection, national defense, the maintenance of public order and safety, immigration services, foreign affairs, and general public administration. It also covers compulsory social security activities.
• The classification of an activity into this major section is not determined by the legal status of the entity—that is, whether or not it is a government agency—but rather by the nature of the activity itself, based on the criteria mentioned above. Activities that fall outside the scope of those described above—even when performed by government agencies—are classified under other major categories according to their specific nature. For instance, the administration of school systems (such as establishing regulations, oversight, and curricula) is classified under this major section (O), whereas actual teaching activities are classified under major section P (Education). Similarly, military or correctional facility hospitals are classified under major section Q (Human Health Activities). Conversely, some activities included in this major section (O) may not necessarily be carried out by government agencies.
