The economy of Kerala is the 9th largest in India, with an annual gross state product (GSP) of in 2020–2021. Per-capita GSP of Kerala during the same period is , the sixth largest in India. In 2019–20, the tertiary sector contributed around 63% of the state's GSVA, compared to 28% by secondary sector, and 8% by primary sector. Kerala's high GDP and productivity figures with higher development figures is often dubbed the "Kerala Phenomenon" or the "Kerala Model" of development by economists, political scientists, and sociologists. This phenomenon arises mainly from Kerala's land reforms, social upliftment of entire communities initiated from the first democratic government of Kerala led by E. M. S. Namboodiripad and subsequently implemented by various governments ruled the state. Kerala's economy is primarily based on the concept of "democratic socialist welfare state".

Kerala is the second-most urbanised major state in the country with 47.7% urban population according to the 2011 Census of India, and has tried to maintain a pan-state economy rather than concentrating in some selected cities to develop.

This has fuelled internal migration to Kerala for low-end jobs, even as Keralites have emigrated—mostly to the Gulf countries—in search of better-paying jobs. Around 3,000,000 Keralites are working abroad, mainly in Persian Gulf; to where migration started with the Gulf Boom. The Kerala Economy is therefore largely dependent on trade in services and resulted remittances. In 2012, the state was the highest receiver of overall remittances to India which stood at Rs. 49,965 Crore (31.2% of the State's GDP), followed by Kerala, Punjab and Uttar Pradesh.
