The common statistic that ‘half of marriages end in divorce’ is bogus

From the article:
But according to the Times, the rise in divorce rates in the 1970s and 1980s was a historical anomaly. It occurred during the same time as a major feminist movement, which changed the way society thought about the role of women in life and in the economy. Women initiate about 70% of today’s divorces.
At the time, the high divorce rate signaled an upward trend that would lead to 50% of marriages ending up in divorce. But that statistic never substantiated itself. Divorce rates began declining in the mid-1980s and continue to do so.
