We get this question all the time and the best we can say is that we don’t know. Based on data produced by the National Survey of Family Growth, 43% of first marriages by women aged 15-44 will end in a “disruption” within 15 years. Disruption is defined as either separation or divorce. As not all separations end in divorce (see Table 33 at the link) is would seem that the 50% figure is an overstatement.
The inestimable Cecil Adams of The Straight Dope takes a look at this “fact” and its probable genesis. While not endorsing this view, anyone writing about marriage and divorce should certainly consider the references he provides.
UPDATED DATA AVAILABLE HERE!
NCHStats 
The National Center for Health Statistics only provides the number of divorce took place in the U.S on a national basis as can be seen here:- http://www.cdc.gov/nchs/fastats/divorce.htm. Statistics are not done based on the individual.
How many of these divorces are the result of one of the spouses taking Anridepressants – they have mega negative side effects – one of the biggies being the blunting of feelings of emotions – love and afffection and there were 300 million scripts written for them last year! They are known as THE DIVORCE PILL.
Has anybody studied the script drug / divorce connection???
KM,
Records of divorce do not have this data. We do not have any information concerning this, although we do have number of antidepressants prescribed.
