International migration has become a significant force in shaping economic and social development worldwide. India is one of the largest countries of origin of migrants, and Kerala plays a key role in the migration process due to its long history of connections with the Gulf Cooperation Council (GCC) countries. This article looks at the trends, patterns, and effects of migration and remittances in India and Kerala, focusing on emigration trends, remittance inflows, variations by district and religion, and the socio-economic effects of migration. The study uses secondary data from the World Bank, the Ministry of Overseas Indian Affairs (MOIA), Kerala Migration Surveys (KMS), and related reports. The findings show that remittances have greatly helped reduce poverty and improve living standards, housing, education, and overall household well-being in Kerala. However, the benefits of migration are not spread evenly across districts and communities. The article also points out the slowing growth of emigration from Kerala and the changing dynamics of migration after the global economic crisis.
