Youth Development Dataset: Structural Foundations of Sustainable Sports Systems (Extension of the Egiazarian Model)

This dataset expands the Egiazarian Model of Sports League Development by establishing youth development as the foundational structural layer of sustainable sports systems. It includes a conceptual research paper and supporting materials analyzing five key determinants of effective youth systems: access, affordability, coaching quality, retention pathways, and institutional alignment. The dataset demonstrates how integrated youth development pathways enable long-term system stability, athlete pipeline formation, and scalable league growth, particularly in emerging market environments. This work functions as a structural extension of the Egiazarian Model and contributes to the development of a unified systemic approach to sports management.
