How do you obtain your demographic information?

Quantcast uses an inference model to characterize audiences of nearly any size. Quantcast has NOT built its model on PII (personally identifiable information), but instead uses a large-scale mathematical model to infer demographics of visitors.

The inference approach is built on a foundation of direct measurement, using numerous data inputs that provide insight into demographic benchmarks. These benchmarks are the foundation for rich content segments used across millions of digital media assets.
