Omg! There have been so many twins lately that I have been supporting in my doula practice! I always like to share info with my people so did some research and look at all these cool twin facts I found!
1-In 1980, one in every 53 babies born in the United States was a twin. By 2009, that number had risen to one in 30, according to a new brief released by the National Center for Health Statistics. Over the three decades, the twin birth rate (number of twins per 1,000 births) rose 76%.
2-Chances of having a twin pregnancy is increased by maternal age (30+).
3-Fraternal twining is genetically predisposed and the result of a woman releasing more than one egg at the same time.
4- Identical twins are the result of a random split of a single egg and cannot be genetically predisposed.
5-Male twins will not have twins unless their wives have the ability to produce two eggs.
6-Identical twins share the same DNA but do not have the same fingerprints.
7-1 in 250 pregnancies can result in identical twins.
8-22% of twins are left handed, compared to 10% in singeltons.
9-Fraternal twin girls have twice the chance of giving birth to twins than singletons.
10-Vanishing twin syndrome: 15-20% percent of all twin pregnancies will miscarry one fetus.
11-Some estimates suggest 1 in 8 people started life as a twin while 1 in 70 actually are a twin.
12-Once you have fraternal twins you are 3 to 4 times more likely to have another set!
13-Nigeria has the highest rate of multiple births and more identical twins.
14-China has the lowest rate for multiple births averaging 1 in 300.
15-A study shows vegans are five times less likely to have twins than women who consume diary.
16-Polar bears most commonly give birth to twins and on rare occasions triplets.
17-Examining 3D ultrasound images, a study in Padova, Italy found fetuses start deliberately interacting at 14 weeks.
18-40% of twins invent their own language.
19-Over 50% of twins are born before 37 weeks.
20-The average birthweight for a twin is 5lb 5 oz.
Now isn't that interesting?!
