Rural-Urban Migration

in Africa
Michael P. TODARO I
I N THE FEW SHORT YEARS since independence, the nations of tropical
Africa have experienced an unprecedented increase in the size of
their urban populations. From Abidjan to Brazzaville to Nairobi,
recorded urban population growth rates of 7 to 10 per cent per annum
are a common phenomenon (see table I). Part of this growth is due to
the rather rapid rates of over-all population increase in Africa, rates
typically around 3 per cent per annum.2 However, by far the most
important contributing factor has been the massive increase in the number
of migrants arriving from surrounding rural areas. Numerous factors,
both economic and non-economic, underlie the decision of peasant
farmers and educated youths to seek the better life  in the rapidly
growing urban centres. In this article I shall examine the relationship
between migration, expected income differentials, and urban employment
in tropical Africa. I shall begin by briefly presenting a theoretical model
of rural-urban migration which places primary emphasis on the economic
motivations for migration. This analytical framework, where appropriate,
will then be used in the main body of the article, which is devoted to an
examination and evaluation of alternative short- and long-run policies
designed to curtail the massive influx of rural migrants and to alleviate
the concomitant growing unemployment problem in urban Africa.
