Google does not provide demographic information related to search data due to privacy and security considerations. Google has strict policies and measures in place to protect the privacy of its users. Sharing demographic data could result in privacy breaches as it could potentially be used to identify individual users.

Trajaan, on the other hand, uses an analysis of search queries to infer demographic information. This method does not involve direct collection of personal or sensitive information but relies on interpretation and categorization of the search queries themselves. For example, if someone searches for "wedding dress for men," the phrase "for men" can provide an indicator that the person is probably male or looking for male items.

This process involves advanced data analytics and natural language processing algorithms to make these inferences without directly accessing or handling any private user data.

While this method cannot guarantee 100% correctness, it does allow for a broad level of demographic segmentation for analysis and marketing purposes.
