Demographically Identifiable Information

Demographically Identifiable Information, or DII, is defined as either individual and/or aggregated data points that allow inferences to be drawn that enable the classification, identification, and/or tracking of both named and/or unnamed individuals, groups of individuals, and/or multiple groups of individuals according to ethnicity, economic class, religion, gender, age, health condition, location, occupation, and/or other demographically defining factors.

DII can include, though is not limited to, personal identifiable information (PII), online data, geographic and geospatial data, environmental data, survey data, census data, and/or any other data set that can – either in isolation or in combination – enable the classification, identification, and/or tracking of a specific demographic categorization constructed by those collecting, aggregating, and/or cross-corroborating the data.
