In epidemiology, data can be classified into several types:
1. Demographic Data: Information such as age, gender, ethnicity, and socioeconomic status. 2. Clinical Data: Includes symptoms, diagnoses, and treatment details. 3. Behavioral Data: Data on lifestyle factors like smoking, physical activity, and diet. 4. Environmental Data: Information on exposure to environmental factors such as pollution, climate, and workplace hazards. 5. Genetic Data: Data on genetic predispositions and family health history.
