Cross section vs Time Series Data

There are two types of data sets based on the time.

Cross-Section Data

Cross section data is collected on the same point in time. There might be different variables but all of them are collected for the same period of the time. So you won't see any time column.

Time-Series Data 

Time series data expands across periods. Same variable is recorded for different time periods.
