Of the 3 million EU citizens living in Great Britain, a third of those alone live in London.

Those EU citizens stand to be affected by the outcome of Brexit. Whether they will be able to continue to live in London after 31 October remains as unclear as the specifics of how Brexit will occur.

A recent map based on the latest census shows just how European the UK's capital is. The bluer a borough is, the more its residents were born in one of the 27 EU member states. The flag over each borough also shows which nationality is most-represented there.

Brent appears to be home to a lot of Irish citizens whereas Lambeth is referred to as 'little Portugal'. Interestingly, the Luxembourg flag crops up for the borough of Camden, which appears to be where they have made their home. The map shows that Camden is the area with the most Luxembourgish residents.

Overall, the map shows the international nature of London, especially evidenced by its multiculturalism in Westminster, where no fewer than nine nationalities share the highest percentage of the borough's residents: Austria, Sweden, Denmark, Finland, Greece, Slovenia, Italy, the Netherlands, and Spain.

As the map shows, a no-deal Brexit would affect the entire city, especially those EU citizens who have made it their home.
