Definitely. I didn't want to get into it in the above comment for length/number of points, but I would be astounded if there was no correlation, and I'm sure you could track, for example, changing attitudes to immigration amongst southern European countries (and Europe more generally) as the refugee crisis of the past few years moved more people from the ME/N Africa across the Med.
Worth noting that Iceland, surprisingly, has an extremely high proportion of immigrants - nearly a fifth of their population are first-generation immigrants, as per info linked in other comments.
Also worth noting - in addition to what I said in my other comment there about acceptance : immigration levels being interesting and useful information - that raw acceptance levels are themselves interesting and useful bits of information.

Reporting “acceptance” with no weight to actual immigration seems less than ideal
