You asked

We would like to map ethnic groups data by gender and 5 year age bands to Clinical Commissioning Group (CCG) level in England and Local Health Boards (LHB) level in Wales. Nomis provides data regarding ethnic groups (23 categories), gender (males, females, all persons) and quite broad age groups to CCG level. The age groups that Nomis provides are too broad for our analysis, could you provide 5 year age bands?

We said

Thank you for your request.

Unfortunately, we do not hold the data you have requested. We may be able to create a bespoke table with your requested variables from the 2011 Census. Any such analysis would fall outside of the Freedom of Information regime, and would be subject to legal frameworks, disclosure control, and agreement of costs. If this is an option you are interested in, you will need to contact Census Customer Services to discuss your requirements further:
