Examine the economic consequences of migration for both, the places of origin and destination.

The economic consequences of migration for both, the places of origin and destination are different. The main advantage which the source gets is the remittance that they receive from the migrants. It is also a significant source of foreign exchange. Around US$ 11 billion was received by Indians as remittances from migrants abroad in 2002. The regions involving significant amounts from migrants are Punjab, Kerala and Tamil Nadu. Internal migrants also send remittances but there amounts are very low as compared to international remittances. These remittances are spent on food, repayment of debts, treatment, marriages, education, agricultural inputs, construction etc. Remittances are the life blood of the economy of many villages in Bihar, Uttar Pradesh, Bihar, Madhya Pradesh and Odisha. Rural to urban migration accounted for the success of green revolution in agriculture. But apart from these benefits, unregulated migration increases the burden in the urban areas and leads to overcrowding. Slum areas have cropped up in many states like Maharashtra, Gujarat, Karnataka, Tamil Nadu and Delhi due to this migration.
