Tamil is one of the official languages of Singapore and written Tamil uses the Tamil script. According to the population census of 2010, 9.2% of the Singaporean population were Indian origins, with approximately 76.7% who spoke Tamil most frequently as their home language. It is a drop from 2000, where Tamil-speaking homes comprised 82.9%. On the other hand, the percentage of Indian Singaporeans speaking languages categorised under "others" have increased from 9.7% in 2005 to 13.8% in 2010. Meanwhile, the percentage of the total population speaking Tamil at home has remained steady, or has even slightly risen over the years, to just above 4%, due to immigration from India and Sri Lanka.
