Many Europeans incorrectly think most migrants live in their countries illegally, a YouGov poll shows. In Britain, Denmark, France, Germany, Italy, and Spain, 44% to 60% of people believed “many” or “somewhat” more migrants were illegal rather than legal. Actual studies show the illegal immigrant numbers are much lower. For example, only 21% of immigrants in France were ever undocumented. In Poland, public opinion was divided on these numbers. The poll found that 49% to 60% across countries want a "large decrease" in migrants allowed into their nations. Around half of respondents supported freezing new migrant arrivals and deporting many recent migrants. Large majorities, between 64% and 82%, opposed any big migration increase. Most also opposed keeping migration levels the same, except in Poland and Denmark. People supported deporting migrants who break rules, claim benefits, seek asylum irregularly, or work illegally in unskilled jobs. Less support existed for removing legal migrants like asylum seekers following due process, students, and skilled workers. Doctors with work visas were least targeted for removal, with only 15%-24% supporting their deportation among those backing mass deportations. Respondents understood cutting legal migration could harm the economy or public services. Most preferred keeping health staff, filling skilled jobs, and attracting top talent over reducing migration. However, fewer accepted reasons like improving the economy or meeting humanitarian obligations to keep migration levels stable. When asked about migration’s impact, 56% to 75% said illegal migration hurt their country. Views on legal migration were mixed; Spaniards were most positive, while French and Germans were more negative. Many believed even legal migration levels were too high. Over half in France, Italy, and Germany felt legal migrants did not share their values or integrate well. YouGov said, "Legal migration dramatically outweighs illegal migration, but immigration concerns go beyond economics. Addressing them means facing deep worries about identity, integration and national values."
