Long-term research refers to studies that are conducted over an extended period of time, spanning months, years, or even decades. This type of research allows for a deeper understanding of complex phenomena, trends, and patterns that unfold over time. Long-term research often involves tracking changes, monitoring progress, and evaluating the impact of interventions or policies over an extended period. It can provide valuable insights into the long-term effects of various factors on individuals, communities, and societies. Additionally, long-term research helps researchers identify trends, make predictions, and inform decision-making processes for the future.
