Population-based

Population-based refers to approaches, strategies, or studies that focus on or are relevant to an entire population, or a significant segment thereof, rather than individuals. It emphasizes interventions and analyses targeting groups, communities, or societies. This can involve broad public health initiatives, epidemiological research, or large-scale data collection and analysis to understand and address population-level trends, risks, and outcomes. It often contrasts with individual-level approaches, focusing on the bigger picture and aiming to improve the health and well-being of a collective.
