i'd say bout maybe 50% percent of most of it, maybe less if the marriage dont go well.

in Eastern part of the world may be more than 50%.

A lot more than unmarried, that's fer sure

I'm not sure that a statistic will help you in this particular case because 'making it' isn't the goal some couples who've been married for 60 years may have. If you were to go back 60 years, divorce was definately not as practiced or as accepted as it is today. There was a time when women (and men) who had had a failed marriage were viewed negatively by the rest of society so much so that many couples stayed married to eachother even though they had no reason to continue the marriage. The only real marriage statistic that has maintained throughout time is the decline of the percentage of successful marriages after the first marriage. (ie less third marriages are successful than second marriages, less fourth marriages are successful than third, etc.)

Definitely an interesting question. I'm afraid I don't know the answer. But for certain, one of the difficulties of reaching a 60th wedding anniversary is having both halves of the couple living that long. If they married at twenty, they would both have passed the average life expectancy by a bit.

This is actually a pretty complicated question. There is really only one way to answer it and that's with a model. Try and stay with me, cause the model will illustrate the complexity of your question. So this model takes 100 couples married in 1950. The men are approximately 26 years old (this was the average age of marriage for men at that time). This year, how many would be celebrating their 58th wedding anniversary? Most of the divorce stats only track the first 20 years of a marriage. About half of the marriages are over before then, but the rate is about 1.5 - 2 % at 20 years of marriage. So, by 1970 50 of our couples are still together, for every year after that btw 1 and 2% get divorced, that would mean by 1980 approx 33 are still together. Do couples continue to divorce after 30 years of marriage? The likelihood is yes. I don't know the number, so I am gonna take a stab at somewhere around 0.5% per year. This means that between 1980 and 2002, 11 of our marriages will bite the dust. That leaves us with 22 marriages. But then you gotta think of death. The average male lives, what, til 78? so, let's for the sake of argument say that of our original married couples half the men will die on or before their 78th birthday - this happened in 2002. So, I am going to then apply that 50% reduction to the 22 and say we're now working with 11 marriages in 2002. But wait, we're only at the 52nd anniversary at this point. I would think we can pretty much forget about divorce at this stage of the game. Death is by far a bigger factor. Checking out the actuarial tables shows us that we will lose another half of the men before their 86th birthday. So, that will leave us with 5.5 marriages Now we factor in the death rate of women. First, we give them an age at marriage of 22. The likelihood of a woman surviving to the age of 82 is better than the man's, but still we will have lost about 40% of them. Some of them could already have been widowed, or divorced. So I can't reduce our final 5.5 by almost half, but I feel justified in knocking off 1.5. That leaves you with my estimation of 4% of marriages surviving 60 years. Probably not accurate, but a lot closer than the guys who answered "50%".

Probably not a lot. Even if the couple were to marry at the young age of 20, they would be 80 years old by their 60th anniversary. The odds of both of them living that long, especially if they waited a few years to get married drop rather quickly. Either way, it has to be a lot higher than with those just living together unmarried.
