The extent of the protection of the QWI micro-data can be measured in two ways: showing the percentage deviation as a measure of the uncertainty about the true value that one can infer from the released value, and the amount of reallocation of small cells (less than five entities in a tabulation cell).⁷ Each cell underlying the tabulation is for a statistic X_kt where k is a cell defined by a combination of age, gender, industry, and county, and for all released time periods for the states at the time of these experiments.⁸ The interested reader may find an example assessment in table 1 of Abowd, Schmutte, and Vilhuber (2018) undistorted, unweighted data.
