Tamil Brahmins are Tamil-speaking Brahmins primarily living in Tamil Nadu , although a few of them have settled in other states like, Andhra Pradesh, Kerala and Karnataka. They can be broadly divided into three religious groups, Gurukkals who follow Saivism, Iyers who follow the Srauta and Smarthas tradition and Iyengars who follow Sri Vaishnavism. Today Brahmins form 2.75% of Tamil Nadu's population.
