Another country which has played a significant role in the EU's immigration policy was also revealed to have largely negative attitudes towards immigration. Turkey, which became home to some 4 million refugees as part of a deal with the European bloc, was the 10th least accepting country for migrants according to the data collected by Gallup.

However, one eastern European country with a traditionally low tolerance of immigration saw an increase in positive and tolerant attitudes. A share of 42% of Polish respondents said that they considered migrants living in the country as something good, up from 29% three years prior.

Which countries are most tolerant of immigration?

Canada topped the list for the countries most accepting of immigration — 94% of respondents had positive views of immigrants living in their country, followed by Iceland and New Zealand. Within the EU, only Sweden and Ireland made it into the top 10.

Despite a series of anti-immigration policies by President Donald Trump's administration in the US, the country came in sixth place for its generally pro-immigration attitudes. When asked about immigrants moving into their neighborhood, 90% of US respondents said this was a good thing.
