Urbanization and the increasing concentration of population in the major urban centers in Latin America is often conceived as the manifestation of a convergent economic process, that of industrialization (Roberts 1978). Internal cityward migration and natural increase are two dominant contributors to the increase in urbanized population throughout most of Latin America and the Caribbean in the last four decades (Elizaga 1965, Clarke 1974, Davis 1972). In Latin American research, studies of internal migration and urbanization have proliferated, investigating regional origins, migration networks, migrant selectivity, aspects of migrant assimilation in the urban social, economic and political realms, and the character and nature of initial settlement (cf. Morse 1971 for a summary of studies written between 1965–70). By and large, previous research has not fully explored the social and spatial dimensions of the process whereby migrants select initial residential sites and subsequently relocate (exceptions include studies by Brown 1972, Cornelius 1975, Davies and Blood 1974, Vaughn and Feindt 1973, Ward 1976). In short, we know very little about the paths a migrant follows between the time he reaches the city and the time he settles into a secure and stable dwelling environment.
