What is the relationship between rural-urban migration and poverty? Th
is article takes up this question, which is by no means new, but about
which there is no consensus. The importance of migration for urban as
well as for rural areas, for poverty and for poverty alleviation poli
cies is considerable, and the article indicates that more research is
needed, particularly taking into account both sides of the migration s
treams. Rates of urbanisation, which have remained low in countries li
ke India, underestimate the importance of migration. Migrants in citie
s continue to maintain close links with, and return to, their areas of
origin, thus limitiing urban population growth and complicating analy
ses and policies. The article, focusing on migration to Calcutta but a
lso drawing on all-India survey data and other evidence, discusses the
following issues: the role of poverty versus inequality in migration;
the migrants' districts of origin; the socio-economic background of m
igrants; the migrants' income and expenditure, compared to non-migrati
ng groups, and whether migrants are able to improve their income over
time.
