By definition, epidemiology is the study (scientific, systematic, and data-driven) of the distribution (frequency, pattern) and determinants (causes, risk factors) of health-related states and events (not just diseases) in specified populations (neighborhood, school, city, state, country, global). Specifically, epidemiology uses science, systems-thinking, and data to determine the underlying causes of different diseases and health outcomes in a population. Epidemiology is defined as “the study of the distribution and determinants of health-related states or events in specified populations and the application of this study to the control of health problems” (17, p. 3).

Epidemiology definition is - a branch of medical science that deals with the incidence, distribution, and control of disease in a population. All the units in a particular group that we are interested in studying and from which a sample may be drawn. Epidemiology is the study and analysis of the distribution (who, when, and where), patterns and determinants of health and disease conditions in defined populations. Epidemiology is a sector of healthcare that involves incidence, dispersal and managing of various diseases and other ailments that adversely affect health. Tracking diseases in a community is just one half of the equation for epidemiologists. Much of the data that epidemiologists collect comes from self-report—from answers provided by people participating in a study. It does not study individual risk (i.e., “personalized medicine”). If it were���that is, if there were no risk factors and nothing that would either cause or prevent a case from occurring other than sheer luck���then we would not be able to determine who is at greatest risk.
