1. Leaders:
- Ralph: He is elected as the chief of the group due to his charisma, fairness, and ability to make rational decisions.
2. Sub-Leaders:
- Jack: Jack's natural leadership abilities are overshadowed by his desire for power and violence, leading him to be a rival of Ralph.
- Simon: A kind-hearted and compassionate boy who forms an alliance with Ralph.
3. Choirboys:
- These boys, initially led by Jack, are characterized by their strong sense of discipline and order, often serving as the workforce of the group.
4. Hunters:
- As led by Jack and composed of the older and more adventurous boys, the hunters focus on obtaining food for the group, but they gradually embrace a more savage lifestyle.
5. Loners:
- Piggy: He is an intelligent boy who lacks physical strength and is often marginalized due to his asthma and weight.
- The littluns: Younger children who are more vulnerable and less involved in the power struggles.
These social classes are in constant flux as the boys struggle to establish a functional society on the island. The tensions and conflicts between these groups drive the narrative and serve as a microcosm of societal dynamics.
