Community health, a fiel within public health, is a discipline that concerns itself with the study and betterment of the health characteristics of biological communities. While the term community can be broadly defined, community health tends to focus on geographic areas rather than people with shared characteristics. The health characteristics of a community are often examined using geographic information system (GIS) software and public health datasets. Some projects, such as InfoShare or GEOPROJ combine GIS with existing datasets, allowing the general public to examine the characteristics of any given community in the United States.
