Which country has highest twins?

Nigeria, particularly the Yoruba people in West Africa, has the world's highest twinning rate, with some areas like Igbo-Ora seeing rates as high as 45-50 sets per 1,000 births, much higher than other regions, likely due to genetic factors and diet. Central Africa generally has the highest twinning rates globally, but Nigeria stands out due to its specific ethnic groups.

Which country has the most twins?

The highest twinning rate in the world is in Igbo-Ora, Nigeria, often called the "Twin Capital of the World," with a rate of approximately 45 to 50 sets of twins per 1,000 live births.

Which ethnicity has the most twins?

The Yoruba people have the highest rate of twinning in the world, at 45–50 twin sets (90–100 twins) per 1,000 live births, possibly because of high consumption of a specific type of yam containing a natural phytoestrogen which may stimulate the ovaries to release an egg from each side.

Which state has the most twins?

The states with the highest rates of twins are Connecticut, Massachusetts, and New Jersey, and the state with the lowest rate is New Mexico.

Who has the highest number of twins?

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.

These Countries Have The Most Pairs Of Twins In The Entire World (HALF THE COUNTRY IS TWINS!?)

Where are most twins born?

The most twins are born in West Africa, particularly in Nigeria, Benin, and Ivory Coast, with the Yoruba ethnic group in Southwest Nigeria having the world's highest rates (around 45-50 per 1000 births), notably in towns like Igbo-Ora, often linked to genetics and possibly a cassava-rich diet, though Central Africa also shows high rates, while Asia and Latin America have lower natural rates. 

Why do Nigerians have so many twins?

Nigerians, particularly the Yoruba people, have an exceptionally high twin birth rate, possibly due to a combination of genetics and diet, especially the consumption of certain yams and okra leaves (ilasa), which contain phytoestrogens that might stimulate multiple egg releases; however, scientific proof is limited, and cultural factors, like the veneration of twins in towns like Igbo-Ora, also play a role, with many locals attributing it to these local foods and traditions. 

Which city has the most twins in the world?

While no single city holds the absolute record, Igbo-Ora, Nigeria, is widely known as the "Twin Capital of the World" for its exceptionally high twin birth rate (around 45-50 per 1,000 births), alongside other locations like Kodinhi, India, and Cândido Godói, Brazil, which also boast remarkable twinning phenomena, often linked to genetics, diet, or founder effects rather than a single proven cause, notes. 

What parent passes down the twin gene?

For fraternal (dizygotic) twins, the genetic tendency for hyperovulation (releasing more than one egg) is often passed through the mother's side, meaning the pregnant parent's genes are key, but the father can carry and pass this trait to his daughters, increasing their future chances. For identical (monozygotic) twins, genetics play a minor role, as they usually occur randomly when one fertilized egg splits, though some rare genetic factors might influence the split.
 

What causes twin pregnancy?

Twin pregnancies are caused by either two eggs being fertilized by two sperm (fraternal twins) or one egg being fertilized and then splitting into two embryos (identical twins), with factors like maternal age, family history (for fraternal), and fertility treatments increasing the chances, according to March of Dimes and UT Southwestern Medical Center. Identical twins share DNA, while fraternal twins are like siblings conceived together, and both types can result from hyperovulation (releasing multiple eggs) or embryo splitting.
 

Do twins share 100% the same DNA?

No, identical twins don't share exactly 100% DNA; they start with nearly identical DNA from one egg but develop small genetic mutations (point mutations) after splitting, plus differences in epigenetics (gene expression) due to environment, making each genome unique, though standard tests usually show them as identical. These tiny mutations, occurring after the embryo divides, create minor genetic variations that explain differences in traits or disease risk, say CNN. 

What race is the most giving birth?

As of 2023, Black people are more than three times as likely as White people to experience a pregnancy-related death (49.4 vs. 14.9 per 100,000 live births) in 2023 (Figure 1). The rate for Hispanic and Asian people is lower compared to that of White people (12.3 and 10.7 vs. 14.9 deaths per 100,000 live births).

How common are twins in the USA?

The twin birth rate in the U.S. has stabilized around 30-32 per 1,000 live births, roughly 1 in 30 pregnancies, though it's seen fluctuations, dipping slightly after peaking in the early 2000s due to increased fertility treatments and later stabilizing with safer single-embryo transfers. While identical twins occur randomly (around 1 in 250 births globally), fraternal twins are influenced by maternal age (higher in older moms) and ethnicity (highest in African Americans), with the overall rate influenced by fertility treatments. 

What gender of twins is most common?

The most common twin gender combination is boy-girl (mixed-gender) for fraternal twins, making up about half of those births, while overall, female twins are slightly more common than male twins due to higher male fetal loss in the womb; identical twins are always the same sex.
 

What is the oldest twin in the world?

Identical twins Umeno Sumiyama (left) and Koume Kodama (right). Two Japanese sisters have been confirmed as the world's oldest living identical twins and the oldest ever identical twins at the age of 107.

Why can't you say siamese twins?

You can still say "Siamese twins," but it's outdated and often replaced by the more accurate and sensitive term, "conjoined twins," because the original term links to historical "freak shows," isn't geographically accurate for most cases (as it comes from Chang and Eng Bunker of Siam, now Thailand), and can feel dehumanizing, similar to outdated terms for other conditions. "Conjoined twins" is the preferred medical and respectful term for twins physically joined in utero. 

What US state has the most twins?

Genetics plays a role in whether a couple is likely to have twins, but geographical information suggests other factors are at play. Which U.S. State has the highest rate of twin births? According to recent data, that would be Massachusetts, with 44.3 twin births per 1,000 births.

Who had 69 children?

The woman with 69 children, holding the Guinness World Record, was Valentina Vassilyeva, an 18th-century Russian peasant who reportedly had 27 pregnancies between 1725 and 1765, resulting in 16 pairs of twins, 7 sets of triplets, and 4 sets of quadruplets, with 67 surviving infancy. Her husband, Feodor Vassilyev, allegedly fathered 87 children in total, including 18 with a second wife. 

Where are the prettiest twins in the world from?

They are from Orange County, California.

Which race is the least fertile?

In the United States, Asian women consistently have the lowest fertility rates, followed by White (non-Hispanic) and American Indian/Alaska Native groups, with Hispanic and Black women generally having higher rates, according to data from sources like Statista, the March of Dimes (PeriStats) https://www.marchofdimes.org/peristats/data?reg=99&top=2&stop=4&lev=1&slev=1&obj=1, and the CDC (Health, United States) https://www.cdc.gov/nchs/hus/topics/births.htm. For example, recent data (around 2022-2023) shows Asians at roughly 1,353 births per 1,000 women, while White (non-Hispanic) women were around 1,568, and Hispanic women were significantly higher. 

Why is Nigeria on the red list?

The UK government says Nigeria was added to the list because: its analysis suggests a strong indication of Omicron in Nigeria. several cases identified in the UK are linked to travel from Nigeria. Nigeria has strong travel links with South Africa, where Omicron was first detected.

Who carries the gene for twins?

The tendency for fraternal twins is genetic and carried by the mother, specifically a gene for hyperovulation (releasing multiple eggs) that she inherits from her mother or father, but it's the woman who ovulates multiple eggs who has twins, not the father. A father can pass the gene to his daughters, increasing their chances, but his own family history of fraternal twins doesn't directly affect his partner's odds, though factors like age, diet, and fertility treatments also play a role. Identical twins, however, are generally not genetic and occur randomly when one fertilized egg splits.
 

Who is more likely to have twins?

People assigned female at birth who are older (especially over 30), have a family history of twins, have had previous pregnancies (especially multiples), are of African-American descent, are taller/larger, or use fertility treatments are more likely to have twins, particularly fraternal twins, because these factors increase the chance of releasing multiple eggs during ovulation.
