Around 8% of the total employees in the organised sector of state are employed in Financial and Insurance activities as in March 2020. Traditional Industries Traditional industries manufacturing items; coir, handlooms, and handicrafts employ around one million people. Kerala supplies 60% of the total global produce of white coir fibre. India's first coir factory was set up in Alleppey in 1859–60. The Central Coir Research Institute was established there in 1959.

Agriculture and livestock Agricultural sector contributes only 7% to the GSDP of Kerala. Kerala produces 97% of national output of pepper, and accounts for 85% of the area under natural rubber in the country. Coconut, tea, coffee, cashew, and spices — including cardamom, vanilla, cinnamon, and nutmeg — comprise a critical agricultural sector. Around 90% of the total cardamom produced in India is from Kerala. India is the second-largest producer of cardamom in world. A key agricultural staple is rice, with some six hundred varieties grown in Kerala's extensive paddy fields. Nevertheless, home gardens comprise a significant portion of the agricultural sector. Related animal husbandry is also important, and is touted by proponents as a means of alleviating rural poverty and unemployment among women, the marginalised, and the landless. Feeding, milking, breeding, management, health care, and concomitant micro-enterprises all provide work for around 3.2 million of Kerala's 5.5 million households.
