Definition of the Metropolitan Areas
• Proposal based on the spatial distribution of some
metropolitan functions
• Use of GIS
• Scale: Census tracts data (380.000+)
Statistical techniquesStatistical techniques
• Density analysis (Kernel model)
• Factor analysis
Data
• Population Census 2001 (residents & commuters)
• Economic Census 2001 (employees)
