Longitudinal surveys

Longitudinal surveys are research methods where the same group of people is studied repeatedly over an extended period. This approach allows researchers to track changes and developments in individuals’ opinions, behaviors, or characteristics over time. By collecting data at multiple points, longitudinal surveys help identify patterns, causes, and effects, providing a deeper understanding of how things evolve. They are commonly used in fields like social sciences, health, and marketing to observe long-term trends and make informed predictions about future outcomes.
