Abstract: This paper reviews almost four decades of contributions on the subject of
supervised regionalization methods. These methods aggregate a set of areas
into a predefined number of spatially contiguous regions while optimizing
certain aggregation criteria. The authors present a taxonomic scheme that
classifies a wide range of regionalization methods into eight groups, based on
the strategy applied for satisfying the spatial contiguity constraint. The
paper concludes by providing a qualitative comparison of these groups in terms
of a set of certain characteristics, and by suggesting future lines of
research for extending and improving these methods.
