"A Comparison on Data Utility between Publishing
Fixed Intervals versus Traditional Cell Suppression
on Tabular Employment Data"
The Bureau of Labor Statistics' Quarterly Census of Employment and
Wages series publishes employment and wage estimates classified by
county and six-digit North American Industry Classification System
level. Unfortunately, due to data disclosure issues, nationally sixty
percent of the county-level detail is suppressed using traditional cell
suppression techniques. Alternative disclosure-protecting techniques
have been proposed, specifically replacing these tabulations with fixedinterval
for the suppressed cells. This paper will focus on comparing
the data utility of these disclosure avoidance techniques. The positives
and negatives of each will be discussed in addition to utility tradeoffs
between the two methodologies. Data simulations will be presented.
