Fifty-Seven Thousand New Zealanders

The BBC built an amazing presentation of Britain's immigration distribution, by British region and country of birth. Here's the page for New Zealand-born people (like me). As you might guess, the place they seem to cluster in is London. Now those 57,000 people is over 1% of the New Zealand total population, which is like three million Americans living in Auckland (I can make infoporn too).

Browsing around the rest of the map you can find the places with the most overseas-born people - number one is Wembley in London at 51.93%. New Zealand also has the highest percentage of high-income earners among its settled population, although the USA tops the charts for new immigrant economic performance.
