MoSPI's Migration in India 2020-21 report, based on PLFS July 2020-June 2021, recorded India's all-India migration rate at 28.9%. For development policy, migration is therefore not a side issue; it directly affects planning for education, livelihoods, housing, transport and urban services.
Within internal migration, rural-origin streams accounted for 73.9%. This included rural-to-rural migration at 55.0% and rural-to-urban migration at 18.9%. Urban-origin streams accounted for the remaining 26.1%. For examination preparation, this distinction matters because migration cannot be reduced only to movement towards cities; movement within rural areas itself forms a very large component of internal migration. The same split helps separate the needs of origin areas and destination areas.
The data have clear governance relevance. Rural livelihood and education planning need an understanding of how people move across locations. Housing, transport and urban-service planning also depend on the size of the migrant population and its origin. For RAS and UPSC, the topic connects with population, urbanisation, employment, rural development and social security. In static GK, it can be linked with census themes, labour-force surveys, the rural economy and urbanisation. In mains answers, the same data can support points on development planning, service delivery and regional inequality.
