Matt Ridley explains that demography does not explain the sudden influx of refugees from Africa to the European Union:
Even the most compassionate of European liberals must wonder at times whether this year’s migration crisis is just the beginning of a 21st-century surge of poor people that will overwhelm the rich countries of our continent. With African populations growing fastest, are we glimpsing a future in which the scenes we saw on the Macedonian border, or on Kos or in the seas around Sicily last week will seem tame?
I don’t think so. The current migration crisis is being driven by war and oppression, not demography. Almost two thirds of the migrants reaching Europe by boat this year are from three small countries: Syria, Afghanistan and Eritrea. These are not even densely populated countries: their combined populations come to less than England’s, let alone Britain’s, and none of them is in the top 20 for population growth rates.
Well then, perhaps that is even more ominous. If these three relatively small countries can cause such turmoil, imagine what would happen if say the more populous countries in Africa fell into similar chaos. Today Africa’s population (north and sub-Saharan) is about 50 per cent larger than Europe’s (East and West). By 2050, when — according to United Nations estimates — Africa’s population will have more than doubled from 1.1 billion to about 2.4 billion people and Europe’s will have shrunk from 740 million to about 709 million, there will be more than three Africans for every European.
Actually, demography is a poor predictor of migration. Nowhere in the world are people leaving countries specifically because of population growth or density. The population density of Germany is five times as high as that of Afghanistan or Eritrea: unlike water, people often move up population gradients. Tiny Eritrea, with only five million people, is a hell-hole for purely political reasons. It has a totalitarian government that tries to make North Korea and the old East Germany look tame: it conscripts every 17-year-old into lifelong and total service of the state. No wonder 3 per cent of its people have already left.
