Perspectives On African Urbanism: “New Methodologies”

Abstract

This article raises questions about sample size and representativity of the remote sensing based urban sampling methodology. It argues that for many purposes a larger sample, than that of the initial study, would be better and complementary sampling procedures such as network analysis and snowball sampling may be indispensable to capture the variation needed to study some specific research topics. It uses the case of recent immigration to Gaborone, Botswana, to illustrate these points.

Key words: Gaborone, Botswana, rural-urban migration, sampling techniques, urbanization, remote sensing.
