Theresa May: High immigration levels prevent 'cohesive society' per BBC News

Two sentences from this BBC report http://www.bbc.co.uk/news/uk-politics-34450887 struck me:

'Net migration rose by 50% to 318,000 last year - with sharp increases from inside and outside the EU.

A total of 641,000 people moved to the UK in 2014, according to the Office for National Statistics.'

641,000 people moving to the UK last year, that's more than the population of Bristol. In fact that number of people would constitute the 11th largest urban area in the UK.
