The Simulacrum imitates some of the data held securely by the Public Health England’s National Cancer Registration and Analysis Service.
The data in the Simulacrum is entirely artificial. It does not contain data about real patients, so users can never identify a real person. It is free to use and allows anyone who wants to use record-level cancer data to do so, safe in the knowledge that while the data feels like the real thing, there is no danger of breaching patient confidentiality.
We have kept the data model – the shape of the data – the same as the real one so that it can be used to write and test queries that would run on the real data.
