Part (a): At the origin migration brings remittances but loses labour; at the destination it supplies workers and growth but strains infrastructure and wages.

Part (b): The Census bases migration on place of birth and place of last residence; the four internal streams are rural–rural, rural–urban, urban–urban and urban–rural.

Migration reshapes the economies of both the places people leave and the places they move to.

In areas of origin, the most important positive effect is the flow of remittances — money sent back by migrants. These remittances are a vital source of income for the families left behind and help pay for children's education, health care, better housing and small investments. States such as Kerala, Uttar Pradesh, Bihar and Rajasthan draw heavily on money earned by migrants elsewhere in India and abroad. Out-migration also eases pressure on scarce land and jobs in overcrowded rural areas. On the negative side, it removes the young, able-bodied and often skilled workers, so farm productivity can fall, fields may be left with fewer hands at sowing and harvest, and the villages are left with a larger share of the elderly, women and children.

In areas of destination, mainly the big cities, the arrival of migrants provides an abundant and cheap supply of labour for industry, construction, transport, domestic work and services, which keeps costs low and drives urban economic growth and expansion. But this rapid inflow overburdens urban infrastructure — housing, water supply, sanitation, electricity and public transport cannot keep pace — leading to the growth of slums and unauthorised settlements. Competition among job-seekers can also depress wages in unskilled and semi-skilled work. Cities like Delhi, Mumbai, Bengaluru and Pune absorb most migrants and gain economically, while the sending regions lag behind, so migration can widen regional inequality.
