Kodinhi is a village in Malappuram district in Kerala. The village is noted for having a high twinning rate although India has one of the lowest twinning rates in the world.
Administered by the Nannambra panchayat, the village came to international attention for the unusually large number of multiple births in the region. The first association of twins in the country, The Twins and Kins Association, was also founded in the village. Latest surveys found the figure to be closer to 204 pairs (408 individuals) of twins, and two sets of triplets. There were around 2000 families in 2008.
According to doctors, they said, this phenomenon is due to chemicals present in water in the Kodinhi area.
