Nearly half of the world’s twins are born in Africa

Abstract : Nearly 1 in every 100 deliveries is a twin birth. Triplet, quadruplet and higher order deliveries occur much more seldom — only once in 10,000 deliveries. Is the incidence of twin births the same everywhere in the world? Do twins grow up like other children? Do they have the same life expectancy? (1) In 1999, out of 2.8 million twins born worldwide, nearly 1.1 million (41%) were born in Africa; 39% were born in Asia, 13% in America, 6% in Europe and 0.5% in Oceania.
