Ukraine is disappearing, for two reasons. It has one of the world’s lowest birth rates at just 1.23 children per female, and one of the world’s highest rates of out-migration. No other country has willed itself out of existence so decisively.
Ukraine’s demographic decline is so pronounced that it should be high on the list of strategic considerations. For what, and for whom, might NATO and Russia go to war?
Ukrainians vote with their feet. Nine million have work abroad, according to the National Security and Defense Council of the Ukraine, and 3.2 million have full-time jobs in other countries. There are only 21 million Ukrainians between the ages of 20 and 55, which suggests that more than two-fifths of prime working-age Ukrainians earn their living elsewhere.
I do not know whether this estimate includes half a million Ukrainian prostitutes working abroad since independence, according to one scholarly estimate.
Even worse, a Wilson Center study reports, Ukraine’s best-educated people are likeliest to leave:
Ukrainians who go abroad to study often view their studies as the first stage of emigration. A survey of Ukrainian students at universities in Poland, Hungary, and the Czech Republic showed that students who studied in these countries had similar motives for doing so. Most said they intended to earn their diplomas in order to work in the EU in the future, since living conditions in Ukraine were unsatisfactory; few planned to return home after graduating. Those who do return may be the ones unable to settle abroad in permanent positions.
