Model answer

In developing countries, migration flows mostly towards a few big cities: Mumbai, Delhi, Lagos, Dhaka, São Paulo. Smaller towns grow far more slowly.

Why big cities attract more

  • Jobs: agglomeration of industry and services; a large informal sector absorbs unskilled workers.
  • Higher wages than in villages or small towns.
  • Networks: earlier migrants from the same village or caste help with housing and work.
  • Services: better schools, hospitals, colleges.
  • Anonymity and freedom: escape from caste and gender restrictions.
  • Investment bias: capitals and ports get more public and private investment.

Conditions in developing countries

  • Agricultural distress pushes people out; small towns lack industry to absorb them.
  • Urban primacy: one city dominates the urban system.
  • Result: slums (about a sixth of urban India's population in the 2011 Census lived in slums), congestion and pressure on services.

Strengthening small and medium towns through industrial corridors and the Smart Cities and AMRUT missions can spread growth more evenly.
