Cross-Sectional Data

Cross-sectional data refers to information collected at a specific point in time from multiple subjects, such as individuals, companies, or locations. Imagine taking a snapshot of various people's income levels today or recording the current sales of different stores simultaneously. This type of data helps analyze differences and relationships among units at that particular moment. Unlike time-series data, which tracks changes over time, cross-sectional data provides a static view, making it useful for comparing, understanding patterns, and making decisions based on the current state of multiple subjects.
