Term: Data Suppression

Glossary Definition

Last Updated: 2011-05-05


At MCHP, data are suppressed (not revealed or published) when the number of persons or events involved is five or less in order to avoid potential identification of individuals in an area. Data are not suppressed when the actual event count is zero. This process of suppressing data is conducted to protect the privacy of study participants.

For CCHS indicators, data was suppressed when the sample size of positive responses from the un-weighted sample was less than10 respondents, or if the Coefficient of Variation calculated from the standard error of the rate was 33.3 or greater (Fransoo et al., 2009).
