Census tables: richness, structure and risk

Lisa Henley

Detailed tables of counts from a census are highly valued by planners for their richness of information, but bring risk of disclosing particulars about individuals. Statistical agencies aim to sift the richness from the risk. We will look at the structures inside some tables, and suggest ways to measure the important features of these structures. We will examine the risks that come with sparseness, and assess the effects on the richness of rounding and suppression methods.
