Researchers estimate that 40%-50% of all first marriages will end in divorce or permanent separation and about 60% – 65% of second marriages will end in divorce. Although divorce has always been a part of American society, divorce has become more common in the last 50 years. Changes in the laws have made divorce much easier. The highest divorce rates ever recorded were in the 1970s and early 1980s. Divorce rates have decreased since that time, but still remain high.
