A dynamic that surprised me when years ago I learned about it was that consistently the most anti-migration electorate is from areas with next to no migration, while areas with the most migration are generally supportive of it. I watched out for this since and it appears to be a general dynamic accross many different wildly different nations. This disparity is usually showing up as a rural-urban divide, with the cities being more migrant friendly. Whether migration is good or bad in pure economic terms is mostly a function of the demography of a country/region. For most industrialized nations more migrations would be economically benefitial, since the own birth rates are too low to even cover the retirement of their own population. But of course for many people migration isn't just a rational economic question, is a much more loaded, symbolic issue —interwoven with questions of identity, self-worth, self-perception, self-confidence and mythological narratives of the own nation. Which is why identity politics is so effective in getting people to vote against their own economic interests.
