The Divorce Surge Is Over, but the Myth Lives On - NYTimes.com: About 70 percent of marriages that began in the 1990s reached their 15th anniversary (excluding those in which a spouse died), up from about 65 percent of those that began in the 1970s and 1980s. Those who married in the 2000s are so far divorcing at even lower rates. If current trends continue, nearly two-thirds of marriages will never involve a divorce, according to data from Justin Wolfers, a University of Michigan economist (who also contributes to The Upshot).
There are many reasons for the drop in divorce, including later marriages, birth control and the rise of so-called love marriages. These same forces have helped reduce the divorce rate in parts of Europe, too. Much of the trend has to do with changing gender roles — whom the feminist revolution helped and whom it left behind.
