The Urban Caribbean studies urbanization in five countries - Costa Rica, Haiti, Guatemala, the Dominican Republic, and Jamaica - during the 1980s and 1990s, when the region's economy shifted from one heavily dependent on imports to one directed more to producing exports. This shift caused producers and entrepreneurs to rely more on microenterprises, thus challenging the informal economy networks of the central cities. Sociologist Alejandro Portes and the other contributors use rich, in-depth data to examine both qualitative and quantitative changes in these five countries. Their research method allows them to make generalizations applicable to all five economies while retaining the concreteness of the similarities and differences that make each country unique.
