Professor Monden explained that, “The twinning rate in Africa is so high because of the high number of dizygotic twins – twins born from two separate eggs – born there." He continued, “This is most likely to be due to genetic differences between the African population and other populations.”
Researchers have long noticed that the Yoruba tribe — whose members live in Nigeria, Benin, Togo, and elsewhere — is a world leader in twins.
In Australia, twins happen in 1 in every 80 births. This means that 1 in 40 Australians is a twin. The birth rate of identical twins is the same around the world and doesn't vary with the mother's age.
Vietnam was the country with the fewest twins (6.2 per 1,000 births) and Benin was the country with the most (27.9 per 1,000).
Because more twins are born in Igbo-Ora than anywhere else in the world, walking through the town might make you feel like you are seeing double. Almost every house has at least one set of twins. The production and birth of two children from the same pregnancy is still relatively uncommon.
IGBO-ORA, Nigeria — Twins appear to be unusually abundant in Nigeria's southwestern city of Igbo-Ora. Nearly every family here has twins or other multiple births, says local chief Jimoh Titiloye. For the past 12 years, the community has organized an annual festival to celebrate twins.
As per the university, MoMo twins are some of the rarest types of twins, making up less than one per cent of all births in the United States. According to Dr Gupta, MoMo twins account for “fewer than 0.1 per cent of all pregnancies and one per cent of identical twins”.
Race. African-American people assigned female at birth are more likely to have twins than any other race. Asian Americans and Native Americans have the lowest rates for twins. White people assigned female at birth have the highest rate of higher-order multiple births (triplets or more).
In and around Mananjary, twins occur slightly less often than the national average of about 2.8 percent of all births in Madagascar, according to Rakoto, but this may be a reflection of the area's taboo, which may discourage birth registrations of twins.
Around the world, the chances of having twins for a couple is 1 per cent, and the rate for China is 0.5 per cent, according to Yu Rong, an obstetrician from Xuanwu Hospital in Beijing.
Australians Anna and Lucy DeCinque call themselves the “most identical twins in the world”, and work to live up to their self-proclaimed title. They're engaged to the same man, have the same bathroom schedule, and work the same job – one for a salary the other as a volunteer, for legal reasons.
Multiple pregnancies make up about 1.5 per cent of births in Australia, with about 4300 sets of twins and just over 80 sets of triplets and higher order multiples born each year.
Twins are more or less equally likely to be female or male. Contrary to popular belief, the incidence of twins doesn't skip generations.
The rate keeps rising for (naturally) two big reasons. More twins are being born now than ever before. Parents are increasingly using in-vitro fertilization and deciding to have children later in life. The twin rate could continue to go up as more nations push these factors higher.
Birth rate - Country rankings
The average for 2021 based on 194 countries was 18.88 births per 1000 people. The highest value was in Niger: 45.29 births per 1000 people and the lowest value was in Hong Kong: 5 births per 1000 people. The indicator is available from 1960 to 2021.
What happened if a mother had twins? The one-child policy was generally accepted to mean one birth per family, meaning if women gave birth to two or more children at the same time, they would not be penalised.
What If A Family In China Had Twins Under The One-Child Policy? That's not a problem. While many stress the one child component of the policy, it's better to understand it as a one birth per family rule. In other words, if a woman gives birth to twins or triplets in one birthing, she won't be penalized in any way.
Originally Answered: What is the law under China's one child policy, if a woman conceives twins? The one child per family policy is a bit of a misnomer. A better way of phrasing it would be a one birth per family policy. Women who give birth to twins, triplets, or more aren't penalized in any way.

In the United States, the highest fertility rates (per 1,000 women ages 15-44) during 2018-2020 (average) were to Hispanic women (64.8), followed by blacks (62.6), American Indian/Alaska Natives (60.8), Asian/Pacific Islanders (55.6) and Whites (55.3).
Septuplets (7)
The Frustaci septuplets (born 21 May 1985, in Orange, California) are the first septuplets to be born in the United States.
Octuplets are a set of eight offspring born at one birth. An individual that is part of such a set is called an octuplet.
Fraternal twins live longer than singletons and identical twins longer still. Male identical twins on average, saw the most benefit. The rarity of twins has inspired many myths about them.
The longest interval between the birth of twins is 90 days, in the case of Molly and Benjamin West, dizygotic (fraternal) twins born in Baltimore, Maryland, USA to parents Lesa and David West (all USA) on 1 January and 30 March 1996.
Can twins have different fathers? In rare cases, fraternal twins can be born from two different fathers in a phenomenon called heteropaternal superfecundation. Although uncommon, rare cases have been documented where a woman is pregnant by two different men at the same time.
