Epidemiology is the study of which of the following?

• A. Diseases
• B. Populations in relation to health
• C. The weather
• D. Careers in medicine

Answer: (B)

Epidemiology examines how health-related states or events occur across groups of people and what factors influence those patterns. It emphasizes the relationship between health and populations, looking at who is affected, where and when, and why, to guide public health actions. That population-focused view is why the description that highlights populations in relation to health is the best fit. It isn’t about weather or careers in medicine, which lie outside the scope of epidemiology.
