Bryan Roberts' study of two poor neighborhoods of Guatemala City is an important contribution to the understanding of the urban social and power organization of underdeveloped countries. It is the first major study of any Central American urban population.

Organizing Strangers gives an account of how poor people cope with an unstable and mobile urban environment, and case material is provided on the emergence of collective action among them. Several themes that are crucial to understanding the significance of urban growth in the underdeveloped world are explored: the impact of city life on rural migrants, the relationship between living in cities and the development of class consciousness, and the changing significance of personal relationships as a means of organizing social and economic life.
