Using 2010 data from the World Bank (though it will soon be updated to reflect more recent migration patterns), this map from the International Organisation for Migration allows users to track both inward and outward migration from any country.
Each circle represents up to 20,000 people, and tracks how many people either emigrated from one country to another or vice versa. So while there were over 500,000 Poles in the UK (a 2013 estimate states there are roughly 700,000), there were over one million Brits in Australia, according to the 2010 data.
Migration works both ways and the privilege/accident of birth that allows certain nationalities to travel freely and restricts others from finding safety from war, conflict and political instability is something we should all be talking about.
