longitudinal data systems

Longitudinal data systems are organized collections of information that track individuals' data over time. They compile records from various sources—such as schools, healthcare, and social services—to provide a comprehensive view of a person’s experiences and outcomes throughout different stages of life. This ongoing tracking helps policymakers and professionals understand patterns, evaluate programs, and make informed decisions to improve education, health, and social services. Essentially, they create a detailed timeline of an individual's interactions with public systems, enabling more effective planning and support.
