How many people live in the European Union?

How to get close to this number

Add the big members and scale. Germany, France, Italy, Spain and Poland together account for roughly two thirds of the bloc, and adding the remaining twenty-two states brings the total to around four hundred and fifty million. Summing the largest members and scaling for the tail is the standard method for any bloc population.

The comparison in the explanation is the calibration that matters: roughly a third more than the United States. That relationship surprises people who think of the bloc as smaller, and it is the single most useful fact for interpreting any European economic or political statistic against an American one.

The departure is the structural event. The bloc peaked above five hundred and ten million and lost sixty-seven million in a single day when one member left — the only time a large political union has shrunk by that much without a war. Population totals for political entities can move discontinuously in a way that national populations never do.
