More surveys and graphs to digest (or to dismiss, meta-analyse, etc. - you know what you're like 😉)
A diversity survey has asked people in a decent range of countries how they would feel about living next door to a range of person-types (drug addicts and people of another religion, unmarried couples living together and heavy drinkers, etc.) Handily turned in to a compare and contrast graph here:

I'm not sure how meaningful these surveys are, especially in cross country comparisons. Self-reported racism sounds like something that can vary a lot from "true" racism because some respondents may prefer to hide or even be in a state of denial (Sweden is a clear example).
Ideally, we would need some sort of indirect evidence.
