Nigeria has the highest twin birth rate in the world, particularly in the Yoruba region where cities like Igbo-Ora are known as the "land of twins," with rates around 45-50 per 1,000 births, significantly higher than the global average, due to genetic factors, hormonal differences, and potentially diet, BBC, Wikipedia, YouTube, National Institutes of Health (NIH) | (.gov). Other African nations like Benin and Ivory Coast also have very high rates, with genetics playing a key role in these dizygotic (fraternal) twins.
The Nigerian town of Igbo-Ora is famous as the world's ''capital'' of twins due to its unusually high number of twins, from the youngest babies to the elderly. Many describe this as a miraculous phenomenon.
One of Africa's largest countries, Nigeria, has been nicknamed “The Land of Twins” by the BBC because it has the highest rate of twin births in the world. In Igbo Ora, in Oyo State in south west Nigeria, the rate is much higher, the last recorded figures revealed an average of 50 sets of twins in every 1,000 births.
In the U.S., twins are most common in African-Americans (36.8 per 1000) and least common in Hispanic/Latino Americans (21.8 per 1000). Over 20% of births to moms over the age of 45 were twins, but only 2% of births to moms under age 24 were twins.
Percy Nylander clarified many of the factors that contribute to this high incidence of twinning. His analyses of Nigerian placentation and zygosity have shown the increased rate of multiple pregnancy to be a result of higher proportions of dizygotic twins and trizygotic triplets as compared to Caucasian populations.

Discussion. In our study, black women had a significantly higher odds of ever having experienced infertility than white women. Even after adjustment for socioeconomic position, marital status, and other risk factors for infertility, this disparity persisted.
High rates of twins are found throughout Central Africa. With 27.9 twins per 1000 births (2.8%), Benin has the highest national average. On the other hand, the twinning rate in Asia and Latin America is very low: often less than 8–10 per 1000 births (0.8–1%).
In fact, studies have shown that women in their late 30s and early 40s are more likely to release multiple eggs in one cycle, which increases the chances of conceiving twins. The body's tendency to release more eggs is one of the reasons why older women have a higher rate of twin pregnancies.
Asian Americans and Native Americans have the lowest rates for twins.
A daisy baby is another name for babies with TTTS. The Twin-to-Twin Transfusion Syndrome Foundation coined the term after its founder planted daisy seeds with her surviving twin son in their backyard. The daisy field is a symbol of hope that all babies affected by TTTS will survive.
They are from Orange County, California.

Substantial increases in twinning rates were observed in many countries in Europe, North America and Asia. For 74 out of 112 countries the increase was more than 10%. Africa is still the continent with highest twinning rates, but Europe, North America and Oceania are catching up rapidly.
For a given pregnancy, the odds of conceiving fraternal twins are only determined by the mother's genetics, not the father's.
Quintuplets (5) The Lyon quintuplets (born 29 April 1896) were the first American quintuplets who were all born alive.
Age: If you're over the age of 35, you're more likely to release multiple eggs during ovulation. Family history: If your mother's side has a history of fraternal twins, there is a chance you could conceive twins naturally.

Benin has 27.9 twin births for every 1,000 live births, which is the highest rate of natural twinning in the world.
Another reason for the rise in twin births is that the average age of women at childbirth has risen . Older women are more likely to have twin births, even without using reproductive technologies.
Proportions of patients with described clinical conditions among different racial groups of patients. Results show significant differences for sperm concentration between different racial groups with Central/South Asian men exhibiting the highest values while Southeast Asians had the lowest (p < 0.0001) ( Figure 1a ).
Skin barrier function is reportedly stronger in darker skin tones (the stratum corneum is the skin barrier). Asian skin is reported to have similarities with Caucasian skin in terms of water loss and has the weakest barrier function.
Hispanics have the youngest, 27.6. Non-Hispanic blacks (32.9) and non-Hispanic Asians (35.9) also are younger than whites. Related to their younger age profiles, racial and ethnic minority groups also include a higher share of women in the prime child-bearing ages of 20-34.
