Data Description

This section should be in two parts.

The first should simply describe the name and source of the data you are using and the period it covers. Describe whether you have a panel, cross$-$section or time series, what the unit of observation is$,$ and how many observations you have. Discuss limitations of the data such as missing variables, missing observations, survey response, small number of observations, etc. You may want to highlight the important limitations $($e$.$g$.,$ those that you might address in a falsification or robustness check later$)$ in the body of the paper and put the rest in a footnote. It is useful to think about what the ideal dataset would be for the hypothesis you want to test and compare your data to it$.$

The second section should present $($relevant$)$ descriptive statistics of the data. You should have a couple of tables with means and standard deviations for the variables you will be using in the analysis. You may want to present these descriptive statistics for different subgroups. The names of the variables should be clear to the reader.
