This document discusses community dynamics and community action. It defines community as a group of people who share common characteristics or interests. Communities can be geographical, based on location, or non-geographical, based on shared social attributes. Studying community is important as it encourages social cooperation, helps people improve their lives, and informs community participation policies. Community dynamics refer to changes within a community from social, cultural, or environmental factors. Community action aims to increase community understanding, engagement, and empowerment to address community issues and provide services. Key aspects of community action are raising awareness, collaborative work, and empowering communities to control their own situations.
