The write-up should describe the variables: the agency which produces the data, the year of the data, and more specific definitions of the data (for example, educational attainment is defined as the share of persons age 25+ who have earned a Bachelor’s degree or higher). The write-up should also comment on the summary statistics. For example, do the minimum and maximum values for the variables seem reasonable or extreme? Are the mean values of the variables large relative to the standard deviations? The write-up might also comment on the region of the country where the 60 to 80 metropolitan areas are located.
