Kerala Migration Survey

The Kerala Migration Survey (KMS), conducted by the Centre for Development Studies (CDS) in Thiruvananthapuram, is a pioneering initiative that has been studying international and internal migration from Kerala since the mid-1980s. Beginning with its first survey in 1998, KMS has completed seven rounds, covering all regions of Kerala and expanding from 10,000 households in 1998 to 25,000 in 2018. This rich dataset provides detailed, disaggregated data at the taluk level, offering valuable insights into emigration, return migration, remittances, and migration costs. KMS is widely regarded as the most reliable and authentic source of migration data, essential for researchers and policymakers alike. The 2018 survey marked KMS as the first exclusive migration survey series to span over two decades, making it a unique and invaluable resource in the global migration research landscape. Data from various rounds are available for download and analysis in multiple formats, encouraging extensive use for research purposes.

自20世纪80年代中期以来，由位于特里凡得琅的印度发展研究中心（CDS）实施的喀拉拉邦移民调查（KMS）是一项开创性的举措，该调查一直致力于研究来自喀拉拉邦的国际和国内移民。始于1998年的首次调查，KMS已完成了七轮调查，覆盖了喀拉拉邦的所有地区，调查范围从1998年的1万户扩展至2018年的2.5万户。这一丰富的数据集提供了详细且按地区分级的塔卢克级别数据，为移民、回流移民、汇款和移民成本等方面提供了宝贵的洞见。KMS被广泛认为是迁移数据最可靠和最权威的来源，对于研究人员和政策制定者而言均不可或缺。2018年的调查使KMS成为首个跨越二十年的独家迁移调查系列，使其在全球迁移研究领域成为独特且极其珍贵的资源。各轮次的数据均以多种格式提供下载和分析，鼓励广泛用于研究目的。
