Sociologists from Ohio State University have found that children from large families have markedly lower divorce rates.

The equation that emerged after a 40-year study, involving a sample of 57,000 American adults, was simple: The more siblings you had as a child, the less likely you were to be divorced as an adult. The researchers don’t offer an explanation for this phenomenon—in fact they seem to be stumped—but they know it’s not because the children from large families don’t marry. On the contrary, they’re more likely to marry, and more likely to stay married, than their small-family counterparts.

We already know that among married couples who don’t use contraceptives, the rate of divorce approaches zero. Obviously these couples are more likely to have multiple children. So by eschewing contraceptives, a married couple is taking a huge step to guard against divorce—not only for themselves, but for their children as well.

Do we know this?

Re: Article

The reasons for it should be blatantly obvious.
The children from large families are conditioned more by the natural world and will become more adept at manipulating their environment to their advantage. Instead of these ridiculous "flings" which are essentially rooted in an incompetence in those who participate, the children from large families will be more in union with their nature, more adept, more capable of spotting bad long term partners and will choose those with whom they can be successful in long term bonds.

School children from large families are better behaved, have more friends, get along with others, and are more apt to be emotionally well-adjusted than their small family or only-child peers.

I totally agree with this statement.  Only children can grow up to be very self-centered adults.  All the big families I know have really cheerful and helpful children.  They seem very comfortable around adults also whereas "only" kids always seem sullen and need to be entertained.

I have to agree with Tiffany. I haven't seen the article to be true in my experiences.
