 Goodwin and Milazzo say that "in areas where there were previously few migrants, increases in immigration will have a more noticeable effect – and will be more likely to influence political behaviour" whereas ethnically diverse areas will perceive additional immigration as having little effect.They go on to explain that the non-British population of Boston in Lincolnshire became 16 times larger between 2005 and 2015, rising from 1,000 to 16,000.Boston also had the highest vote in favour of 'leave' in the UK, at just over 75% in favour of leaving the EU, which they believe is due to the effects of immigration seeming sudden and intense.
