Kerala has a population of approximately 34.6 million, accounting for nearly 2.8% of India's total population. The state boasts the highest literacy rate in India, consistently reported above 96%, alongside the highest life expectancy and lowest infant mortality rates in the country.
The demographic composition is distinct for its religious diversity and harmony. According to the 2011 census, Hindus make up about 54.7% of the population, Muslims 26.6%, and Christians 18.4%. Malayalam is the official language and the mother tongue of the vast majority, though English is widely spoken and utilized in business and higher education.
Unlike much of India, Kerala is experiencing a demographic transition marked by a low birth rate and a rapidly aging population. Furthermore, the state has a unique urban-rural continuum, where towns and villages blend seamlessly into one another, leading to a highly dispersed population pattern rather than massive, concentrated megacities.
