“The public generally do not understand the difference between operational and statistical uses of personal data” say ONS. They are right. Unfortunately, neither do other people who probably should.
The ODI has recently published a draft data spectrum which recognises that there are a variety of areas of tradeoff and differences.
The Chief Data Officer is not about statistical uses of data – it is serving very different user needs (user needs, not departmental needs) – it is/was about using data to improve operations. Why do you think Whitehall was so terrified?
