“It is estimated that the general American divorce rate for marriages made between 1970 and 1985 is 50 percent. Rates of divorce among American Jews are somewhat lower, with approximately one of every three or four marriages predicted to end in divorce. The percentages scale downward depending on degree of religiousness, with close to 50 percent predicted for the general Jewish population in most urban centers, while a quarter of modern Orthodox marriages are destined for
failure, and divorces among the ultraOrthodox will hover at over 10 percent. All the rates for divorce are the highest in the history of Judaism.”
