national and state-level data

National-level data refers to information collected across the entire country, providing an overview of trends, behaviors, or conditions at a broad scale. State-level data focuses on individual states, offering insights specific to regional or local contexts, which may vary within the country. Both are important for understanding overall patterns and regional differences, guiding policymakers and researchers in making informed decisions. While national data shows the big picture, state data highlights variations and specific needs within particular regions.
