Assam, which increased to nine by the time of the 2011 census. Kerala The population of Hindus in Kerala has more than doubled from 8,344,351 in 1951 to 18,282,492 in 2011 census, but the share of Hindu population has dropped from 68.5% in 1901 to 54.7% in 2011. Manipur A decrease in the 1991–2001 period is observed in Manipur, from 57% to 52% population share, where there has been a resurgence of the indigenous Sanamahi religion. The Hindu population share in Manipur also decreased in 2001–2011 from 52% to 41.4%. The religious conversion of Hindus to Christianity and migration of Christians from Nagaland are considered to be the reason for this decrease in the Hindu population. Law & politics Most Right Wing Hindu organisations like RSS, Bajrang Dal, Vishwa Hindu Parishad have demanded that India should be declared a "Hindu nation" by constitution to safeguard the rights and life of Hindus in this largest democracy. As far as citizens are concerned, only 7/20th Indian Hindus are in the favour of making India as Hindu Rashtra. Nearly two-thirds of Indian Hindus (64% of the population) say's that it is very important to be Hindu to be truly Indian or citizen of India. As of 28 July 2020, there were pleas going on Supreme Court of India to remove the words secular and socialist from the Preamble to the Constitution of India. Recently ex-Rajya Sabha MP Subramanian Swamy's have made Plead to Supreme Court of India for Deletion of "Socialist" & "Secular" words from Preamble to the Constitution of India. Controversy Although the Constitution of India has declared the nation as a secular state with no state religion, it has been argued several times that the Indian state privileges Hinduism as state sponsored religion constitutionally, legislatively and culturally. The original copy of the Indian constitution has the illustration of Lord Ram, Sita, and Lakshman in Part III on Fundamental Rights and Lord Rama has been considered as the true guardian of people's rights. Article 343 (1) of the Indian Constitution also states that, "The official language of the Union shall be Hindi in Devanagari script". Also, Article 48 of Indian constitution prohibits the slaughter of cows or calves (a sacred animal in Hinduism) and it is a criminal offense in most of the states of India.
