Answer:
Its publisher and date of publication
Explanation:
Along with the numerical data that indicate the percentage of total withdrawals and the cumulative percentage of total withdrawals in each of the five states, it is necessary to indicate who published it and when it was published so that the data collected do not seem biased. Without this information, readers would not be able to search for the information in other places and would not be able to confirm the data reliability and the publisher's credibility.
