Definitions
In Brazil, the terms metropolitan area and urban agglomeration have specific meanings. They are defined by federal and state legislation as collections of municipalities focused on "integrating the organization, planning and execution of public functions of common interest". An integrated development area is one of the two above structures that crosses state boundaries.Because these regions are formed by consent of municipalities, their composition can change over time due to municipal reorganization. These regions may not coincide exactly with boundaries of statistical Immediate Geographic Areas defined by IBGE, or with the broader definition of built-up urban area.
