Community effects refer to the impact that individuals, groups, or organizations have on the social, economic, and environmental aspects of a community. These effects can be positive, such as increased social cohesion or economic growth, or negative, like pollution or crime. Understanding these effects helps in planning and implementing policies that benefit the community as a whole. Additionally, community effects can influence public health, education, and overall quality of life. For instance, access to public parks can promote physical activity, while community centers can provide essential services and foster social connections. Recognizing these dynamics is crucial for sustainable community development.
