I read somewhere that twins occur 1 in 100 births. But I don't know if that includes both fraternal and identical twins. It also seems twins are more common than that, because I've met tons of people who have twins. Does anyone know?

Here's a quote from Wikipedia: "North American dizygotic (frats) twinning occurs about once in 83 conceptions." But they don't seem to have figures for monozygotic. Another site gives this for identicals: "3.5 per 1000 ( 1 in 285) (this figure seems to be universal and random)" Of course, many of the fraternal twins you see today are the result of fertility drugs and IVF. Also, some of the identicals may come from fertility treatment, because there seems to be a greater tendency of embryos to split than in natural conception. And older mothers are also more likely to be twin moms.

But in our area, the D.C. area, where women have deferred childbearing and the population is affluent and can afford fertility treatment, there are piles of twins. I was in the Costco when the twins were babies, and this woman comes over and says, "Oooohhhh, are they twins?" And I replied that they were. And she said, "They're the third pair I've seen in here today!" OK. You're in my face going gaga over my twins, and you've already seen two other sets in the store just today?

Take care,

As Maggie mentioned the fact that living in an urbsn setting does drive the twin rate up higher since many women delay child bearing until their later years, then twins occur more often as in many cases they are using fertility assistance to create their family. Also, if they are "running out of time" they may be willing to risk multiples and even perhaps in some cases seek them out to complete their family.

I live in an area where most women have their children at a younger age and I haven't encountered a lot of twins. 0ur multiples group is very small and sets of twins are not a regular occurance, either that or multiple moms don't seek us out.

Having said that when I go to our nearby city and visit Costco's, like Maggie said...that is when I meet the most twins/families....could be because we are buying in bulk and feeding a tribe. I took our newborn twins there when they were in their frame stroller with their two identical car seats snapped in and we wouldn't even get down one aisle and we would be stopped and asked..."are those twins?"...it used to drive me crazy because first the babies were in identical car seats..riding in the same stroller set up....and they were dressed identically....then the next question I would hear after answering yes they are twins would be...."are they identical." aaaAHHHHH! I usually answered no and smiled and kept walking because inevitably the next question we would get...because I'm an older mom is..."did you use IVF?"

When we met other families with twins, we just smiled at each other and usually there was no batter about are those twins...yes...we knew they were twins and we just wanted to shop and get out of the store.

Sometimes I wish twins were more common in our hometown because it feels like we are a side show...between the fact that we have 8 kids, we are older parents AND we have twin girls...there are a lot of questions. It has really taught me the lesson of tact and being polite from what I experience around our town.

Still there is my immense gratitude that I had the opportunity to bring these babies to earth and they are a apart of our family...that is worth all the questions in the world. Twins are a blessing and perhaps that interets other people...and then there are some who have problems dealing with one baby and their are in awe over moms with multiples. Whatever the issue, it has been so worth having twins...even all the annoying questions...and besides we have the choice to go out or not.

Blessings from Hope

If Frats occur 1 in 83 conceptions, what is the live birth statistic?

I don't know if that percentage has decreased, but a 37%? I had no idea it was that high. Only 1 in 4 DE births were considered to be singletons of healthy birth weight and full term.

That 1/4 DE cycles has the ideal outcome (live birth of a singleton of healthy weight). As opposed to births.

For instance in the article it appears to say that only 56% of DE pregnancies proceeded to live birth and if that was true it would be a horrendous miscarriage rate. Rather I think they mean 56% of DE CYCLES had a live birth. That would make more sense.
