Say I get married, the odds of me getting a divorce in a year or less are 11.5% and the chances for divorce for marriages between 1-5 years is 15.7%. My first question is, would adding them up be a good approximation for the odds of divorce in 5 years? Bearing in mind that the total number of marriages and divorces are 9597 and 4261 respectively. My main question though is, if the odds of divorce for husbands in the age group of 25-29 is around 27%. And for the group of 30-34 the divorce rate is ~21%. How can you calculate the divorce rate for someone who married at 28 while also taking into account the length of the marriage? I feel like my question isn't clear but I'm not sure how to explain it better than this.
