Dear Lord Wigley,

As National Statistician and Chief Executive of the UK Statistics Authority, I am responding to your Parliamentary Question asking what conversations have been had with the Welsh Government about seeking to include statistics on the number of people resident in England who can speak, read or write in the Welsh language in the 2031 census (HL2487).

The Office for National Statistics (ONS) is developing its population and migration statistics by further expanding the range of data sources and methods it uses. A key focus of the Future Population and Migration Statistics (FPMS) Programme is continuing to expand the use of administrative data to produce population and migration statistics, working across the public sector to maximise the statistical value of its data assets. The FPMS will create a sustainable statistics system that will be flexible and dynamic in how it responds to the emerging issues of the day. The UK Statistics Authority (the Authority) plans to publish a recommendation to government in the coming months.

Decisions about the 2031 census have not yet been made. As such, topics for inclusion in a 2031 census have not formed part of the ONS’ discussions with the Welsh Government or other stakeholders. The FPMS programme has an ongoing programme of user needs engagement and carried out a consultation in 2023[1], which acknowledged the importance of collecting data on this topic. The consultation document categorised Welsh language skills as a topic for which further research is required into delivering statistics primarily based on administrative data. Welsh language is regarded as a priority characteristic within the FPMS programme with exploratory work on this topic ongoing. However, it is likely that data on Welsh language skills will predominantly come from sources relating to people resident in Wales.

In April 2023, the ONS and Welsh Government published a joint work plan on the coherence of Welsh language statistics produced from different sources[2]. The first project, to understand differences between Census 2021 and household survey estimates, has been completed. Other work outlined in the plan is ongoing, with the next priority looking at comparing Census 2021 with the Welsh School Census and other administrative sources. Welsh Government and ONS teams meet monthly to discuss progress and are arranging a secondment from Welsh Government to the ONS to support work on the planned projects. The ONS is also exploring the feasibility of producing Welsh language estimates through using existing administrative sources, with the involvement of Welsh Government.

Yours sincerely,

Professor Sir Ian Diamond
