Defining the target population is crucial for several reasons:
1. Relevance: It ensures that the research findings are applicable to the group of interest. 2. Resource Allocation: Helps in the efficient allocation of resources for public health interventions. 3. Precision: Improves the precision of the study by reducing variability and focusing on a specific group. 4. Generalizability: A well-defined target population allows for better interpretation and generalization of the study findings to similar groups.
