When a pressure group is made up of people of the same profession, it is called an "occupational group". This means that the individuals in the group share a common profession or occupation and seek to promote and protect their common interests, needs, and goals through collective action.

These groups often engage in lobbying activities to influence government policies and regulations that affect their profession.
