 Some research suggests that anti-immigration views are transmitted from older generations to younger generations.A 2017 study of Germany found "high association between fathers' and sons' right-wing extremist attitudes".A 2015 study found that British communities that were more acceptant of Jews in medieval times show much more tolerance towards 20th century immigrants (chiefly Caribbean and South Asian immigrants) and 21st century immigrants (chiefly Eastern European), and less support for the far right.
