The twin town of Kodinho In the south of India, there is a village with a mystery. More twins are born in Kodinho, in the state of Kerala, than anywhere else in the world. Doctors really don't know why although they probably have some ideas. The country with the biggest number of twins is Nigeria. In general, Asia is the continent with the lowest number of twins - only 4 sets per 1,000 babies. China has one of the lowest numbers with 1 birth in 300 being multiple. Yet in Kodinhu 45 sets of twins are born per 1,000 babies, which is nearly six times the global average. At the last count, there were 220 sets of twins among Kodinhu's 2,000 families. In the village, there is a special association called TAKA for families with twins. This association aims to help parents with twins because it is very expensive to have two children at the same time.
