The Data Services & Analytics unit holds information on 650 million people and has been accused of creating a “super database”

A data analytics team close to the heart of government has collected data on more than 650 million people, including children under the age of 13, according to newly unearthed documents.

The Data Services & Analytics unit is described as “one of the most advanced data analytics centres in government” and forms part of the Home Office’s Digital, Data and Technology (DDaT) department. It builds decision-making tools and provides data-driven insights to the rest of the Home Office – although details of exactly what it does remain tightly guarded.
