  • Summary

    AP Human Geography Unit 7: Industrial & Economic Development Patterns & Processes

  • Development theory made simple: Rostow's Stages, Wallerstein's World Systems Theory, Weber's Least Cost Theory, and dependency theory, paired with clear diagrams and real-world trade examples. Great for tying together the "why" behind global economic patterns.
