Developmental_And_Economic_Society_Type represents comprehensive social formations organised around distinct modes of economic production, technological capabilities, and social organisation that characterise different stages of societal development and economic complexity. These aggregates reflect how societies have evolved different approaches to organizing production, managing resources, and structuring social relationships based on their technological capabilities and environmental contexts. They demonstrate the relationship between economic organisation and social structure, showing how different modes of production generate distinct patterns of social stratification, cultural practices, and institutional arrangements. These society types illustrate both historical progression in human social organisation and contemporary diversity in approaches to economic and social development across the global system.
