According to Eurostat, the European Union’s statistical agency, the probability of marriage before age 50 has been plummeting for European women and men, while the chance of divorce for those who do marry has been soaring. In Belgium—the birth-land of the scholars who initially detected this Second Transition—the likelihood of a first marriage for a woman of reproductive age is now down to 40%, and the likelihood of divorce is over 50%. This means that in Belgium the odds of getting married and staying married are under one in five. A number of other European countries have similar or even lower odds.
Europe has also seen a surge in “child-free” adults—voluntary childlessness. The proportion of childless 40-something women is one in five for Sweden and Switzerland, and one in four for Italy. In Berlin and in the German city-state of Hamburg, it’s nearly one in three, and rising swiftly. Europe’s most rapidly growing family type is the one-person household: the home not only child-free, but partner- and relative-free as well. In Western Europe, nearly one home in three (32%) is already a one-person unit, while in autonomy-prizing Denmark the number exceeds 45%. The rise of the one-person home coincides with population aging. But it is not primarily driven by the graying of European society, at least thus far: Over twice as many Danes under 65 are living alone as those over 65.
…Given recent trajectories, demographers Miho Iwasawa and Ryuichi Kaneko project that a Japanese woman born in 1990 stands less than even odds of getting married and staying married to age 50.
