All this did not change anything in Goa. Finally, fed up with the delay, Konkani activists launched an agitation in 1986, demanding official status for Konkani. The agitation turned violent in various places, resulting in the death of six agitators from the Catholic community: Floriano Vaz from Gogal Margao, Aldrin Fernandes, Mathew Faria, C. J. Dias, John Fernandes, and Joaquim Pereira, all from Agaçaim. Finally, on 4 February 1987, the Goa Legislative Assembly passed the Official Language Bill, making Konkani the official language of Goa. Konkani was included in the Eighth Schedule to the Constitution of India as per the Seventy-First Amendment on 20 August 1992, adding it to the list of official languages. Geographical distribution The Konkani language originated and is spoken widely in the western coastal region of India known as Konkan. The native lands historically inhabited by Konkani people include the Konkan division of Maharashtra, the state of Goa and the territory of Daman, the Uttara Kannada, Udupi & Dakshina Kannada districts of Karnataka, along with many districts in Kerala such as Kasaragod, Kochi, Alappuzha, Thiruvananthapuram and Kottayam. All of the regions and areas have developed distinct dialects, pronunciation and prose styles, vocabulary, tone and sometimes, significant differences in grammar. According to the 2001 estimates of the Census Department of India, there were 2,489,016 Konkani speakers in India. The Census Department of India, 2011 figures put the number of Konkani speakers in India as 2,256,502 making up 0.19% of India's population. Out of these, 788,294 were in Karnataka, 964,305 in Goa, 399,255 in Maharashtra, and 69,449 in Kerala. It ranks 19th on the List of Scheduled Languages by strength. The number of Konkani speakers in India fell by 9.34% in the decade 2001-2011. It is the only scheduled language apart from Urdu to have a negative growth rate in the decade. A very large number of Konkanis live outside India, either as expatriates (NRIs) with work visas or as naturalised citizens and permanent residents of other host countries (immigrants). Determining their numbers is difficult since Konkani is a minority language that is very often not recognised by censuses and surveys of various government agencies and NGOs catering to Indians abroad. During the days of Portuguese Goa and British rule in Pre-Partition India many Goans and non-Goan Konkani people went to foreign countries as economic migrants to the Portuguese and British Empires, and to the Pakistan of Pre-Partition
