WebFinally, there is panel data which is more like a movie than a snapshot because it tracks particular people, rms, cities, etc. over time. Table 3 provides an example of a panel data set because we observe each city iin the data set at two points in time (the year 2000 and 2001). In summary, the data set has 100 cities but 200 observations.
