HIERARQUIA URBANA E CRIAÇÃO DE MUNICÍPIOS: ANÁLISE ESPACIAL DOS IMPACTOS DA CRIAÇÃO DE MUNICÍPIOS NOS POLOS REGIONAIS NOS PERÍODOS DEMOCRÁTICOS DE 1946-1964 E PÓS-1988.

The democratic periods of the XX century, the Populist Period (1946-1964) and recent democratization after 1988 were clear cycles of strong decentralization, and a common set of decentralization measures regarding political and fiscal aspects favored the occurrence of two intense cycle of creation of new municipalities associated to these democratic periods. Another common aspect is that on both periods 1946-64 and after 1988, more than 80% of the municipalities created have a very small population associated with very low urban functions. During 1946 to 1964 more than 2.000 new municipalities were created and after 1988 more than 1.400 which represents 65% of total number of municipalities today, but also more 80% of the municipalities with less than 10 thousand people and 95% of the municipalities with less than 2000. The spatial concentration of this phenomenon on particular regions makes this still more interesting because some states and particular regions on those states concentrated most of the new small municipalities, and also benefited some particular regional urban poles while the creation of small municipalities increases the federal transfer to some particular regions but also to some particular pole’s hinterland favoring some instead of others regions and poles.
