These accomplishments are the standouts that demonstrate how public health has improved population health in our country(Martin, 2020). Everything pertaining to society and health is covered. More crucially, if preventive actions are taken as directed, public health helps to lower healthcare burdens including mortality and treatment costs.

According to Sharfstein (2014), about a decade ago, researchers defined the term “population health” to mean the “health outcomes of a group of individuals, including the distribution of such outcomes within the group.” Their goal was to broaden the discussion of health policy in the United States beyond the “biomedical paradigm” and to encourage investigation into and policy development of the underlying causes of illness. As initially conceived, the term encompassed the impact of income inequality, educational differences, and unjust disparities. Since then, population health has come to mean many different things.
