Which EU country is the most diverse and accepting in percentage terms?

I know it's a pretty controversial topic but I was just interested.
I live in Germany and here the proportion of people with a migrant background is around 29-30%.

What does it actually look like in other countries? Because you can't find any figures for countries like France.

I know that many of the locals are currently leaning more towards the right. But what do you think is the country that most accepts people with a migration background and treats them like natives.

thanks for every answer!
