Thank you, Llywydd. Happy new year to you, Minister. I'm sure that you are as concerned as I am about the decrease in the use of the Welsh language in the report outlined in the census results for 2021. In your response to a question from Heledd Fychan on this issue before Christmas, you said that some data sources show an increase in the use of the Welsh language, whilst others, including the census, show a decline. This inconsistency in the data is a problem because we need accurate information to make good decisions about the future of the language. 

Bearing that in mind, what is the Welsh Government doing to ensure that all of the methods of gathering data are accurate and consistent, and on the basis of what data should we judge the success of 'Cymraeg 2050'?
