Migration seen in the light of core-periphery relations indicates that at the initial stages of development the core will overwhelmingly attract migrants from the periphery.
But as development ‘diffuses’ over time due to the shift in understanding from development as economic growth to that of distributive justice, the strength of the core diminishes. The erosion of traditional values and the equalisation in values between the core and the periphery is important in the reversals.
Educational facilities and other infrastructural services increases wellbeing in the peripheries and open up economic opportunities for employment. These in conjunction with diseconomies of scale developing in the old cores acts as a disincentive for migration or creation of reverse migration.
