What is the difference between Sparta and Athens social structure?

Sparta's social structure was primarily militaristic and hierarchical, with a rigid system divided into three main classes: the ruling Spartiates (full citizens), the Perioikoi (free non-citizens), and the Helots (state-owned serfs). In contrast, Athens had a more diverse social structure that included citizens, metics (resident aliens), and slaves, with citizenship being more inclusive and focusing on political participation and intellectual pursuits. While Spartiates prioritized military training and discipline, Athenians valued education, arts, and democracy. This fundamental difference shaped their respective cultures and lifestyles.
