Multiple studies show that a female’s race/ethnicity is another factor that can affect her chances of conceiving more than one baby at the same time. Some ethnicities increase the probability, while others significantly lower it. This will be explained further in the article
Are Multiple Births Common?
Generally speaking, it’s very rare for any woman to have multiples, as there’s only around a 3% chance of that occurring. Like mentioned, many factors can affect the chances of having a multiple pregnancy.
Ethnicity for one is very significant. According to studies, there’s a lower chance for Asians, especially those from East Asian countries, including the Philippines. On the other hand, African countries still produce the most number of multiple pregnancies all around the world.
However, there’s recent research that shows an increase in the number of twin pregnancies, the most common type of multiple birth, over the past few years. This is most especially apparent in the Western part of the globe.
