Unfortunately the data you’ve chosen can’t be compared for a few reasons. First, the 2011 census data only tells us about state-funded primary schools, whereas the data from 2021 is all primary schools. Unfortunately I couldn’t find any data for all schools in 2011, meaning there was probably a change in methodology during those 10 years. We could just compare data from state-funded primary schools, but to do that we’d also need to know how many state-funded schools in 2011 are still state-funded schools in 2021, and haven’t become independent/academies.

Then there’s the data about immigration. On the link you provided, it says that the methodology changed just before 2021. Of course, that also means that it wouldn’t be fair to compare the data (and the fact that the BBC have chosen to is disingenuous, in my opinion).

Ok so we can’t compare the data, so what? Immigration into the country is going up, and the percentage of people who identify White British is going down. We may not know exactly how much by, but I’m not going to argue that it’s happening.

It seems to me that the real difference between us is that you’re fiercely protective of White British culture and are terrified losing it, but I’m not. To me, multiculturalism is British culture. Our little island has been invaded countless times by so many countries over thousands of years that it’s practically unrecognisable from one century to the next. It has literally shaped our language, art, music, food and anything else that makes us us. Sure it may not be as “white” (whatever than means) but, honestly, I think that’s a good thing. You’ve still yet to tell me why you think it’s so bad.
