What is a rehearsal?
A rehearsal is a smaller-scale version of the main census. It took part in selected areas accross Northern Ireland in October 2021.
Thank you to all who took part. The rehearsal helps us plan for the 2021 Census. Find out more about the census.
Why we held a rehearsal
Carrying out a census is a huge task. A full end to end rehearsal was necessary to ensure that all of our processes, systems and services are effective and working as they should before the 2021 Census. The rehearsal helps us ensure that all elements of the field operation and supporting public interface services (for example, the online self-help system and contact centre) are fit-for-purpose, and the collected information will be used to assure the performance of key parts of the data processing system developed by NISRA.
