There's no perfect answer to this question. Twins can be born into any family. However, The Lancet suggests that there are some currently known reasons that may explain who is more likely to have twins.
- In vitro fertilization (with multiple embryos)
- Genes -- the full scope of genes is not yet known when it comes to twins but most current science believes that we will be able to know from genes one day who will and won't conceive twins.
- Age -- older women statistically conceive fraternal twins more often then their younger peers. Sadly the study I read on this noted "older" women as in their 30s (hey now, that's hardly old!)
- A couple of studies have reported findings that support animal product eaters as more likely to conceive twins. And to that I say, thank goodness I was a vegetarian when I conceived Cedar. Twins are adorable but just one baby for me was so tough. I'm in awe of parents who have multiples.
