We want to think of time dimension and spatial dimension: annual, quarterly, monthly measures and physical units measure (individuals, states, countries, etc. There is time-series measure (spatial dimension is the same and. Dv measured at multiple points of time) and cross-sectional measure (time dimension is the same and dv measured for multiple spatial units).
