Disclosure Avoidance for Census 2010 and American Community Survey Five-year Tabular Data Products

Laura Zayatz, Jason Lucero, Paul Massell, and Asoka Ramanayake


This paper describes the statistical disclosure avoidance techniques to be used for all U.S. Census 2010 and American Community Survey (ACS) five-year tabular data products. Many of these tables are published for very small geographic areas. The paper includes procedures for standard base tables, special tabulations, and a future online query system. Procedures include data swapping, rounding, collapsing categories, applying thresholds, table suppression, and generation of synthetic data.
