An interactive map that shows how many foreign Europeans are currently living in other European countries (the figures reflect only the officially resident).

More than half a million Poles live in the UK, and almost the same number again in Germany. Germany also has 556,000 Italians living there. There are 391,000 Britons in Spain, and more Germans than I imagined living in the UK – nearly 300,000.

The work, to be published in PloS One, revealed a core of 1318 companies with interlocking ownerships. Each of the 1318 had ties to two or more other companies, and on average they were connected to 20. What’s more, although they represented 20 per cent of global operating revenues, the 1318 appeared to collectively own through their shares the majority of the world’s large blue chip and manufacturing firms - the “real” economy - representing a further 60 per cent of global revenues.

When the team further untangled the web of ownership, it found much of it tracked back to a “super-entity” of 147 even more tightly knit companies - all of their ownership was held by other members of the super-entity - that controlled 40 per cent of the total wealth in the network. “In effect, less than 1 per cent of the companies were able to control 40 per cent of the entire network,” says Glattfelder. Most were financial institutions. The top 20 included Barclays Bank, JPMorgan Chase & Co, and The Goldman Sachs Group.
