This chapter presents the results of a research exercise that addressed the characterization of the Coffee Belt APR, from a morphological and functional perspective, and the study of the existing metropolization relations based on the observed demographic dynamics. Regarding the results, the APR is configured as a polycentric region with four main nuclei, the departmental capitals and the municipality of La Dorada, capitals that exercise a prima facie condition in their departments and that from their hierarchy have promoted metropolitan processes around them.
