I am not sure I understand your question. If you are asking which population (which kind of people) are utilitarians, they are from all walks of life. The philosophy was created by John Stuart Mill and Jeremy Bentham, both of whom were British. But it has influenced people all over the world. However, if you are asking what a basic proposition (a belief or theory) of utilitarianism is, this philosophy proposes that an ethical action is one that will provide the greatest happiness for the greatest number of people.
Utilitarianism is the ethical theory that actions are right if they promote the greatest happiness for the greatest number of people. It emphasizes maximizing overall well-being and happiness as the ultimate goal of morality.
The noun utilitarianism is used as a subject or an object; for example: Subject: Utilitarianism is included in this philosophy course. Object: Part of this philosophy course covers utilitarianism.
It collapses into Act-Utilitarianism.
