"The purpose of this study is to examine the demographic evolution of the Brazilian homogeneous microregions in the period 1970/80. It is based on the relative variations observed [in] the population as a whole.... Microregional unities were classified according to the intensity of their populational increase and loss. The different classes were spatially identified in order to establish the relation between demographic growth and the characteristics of the areas." (summary in ENG)
