This paper proposed a methodology to disaggregate population data provided in census tracts into smaller spatial units based on ancillary environmental data and geoinformation techniques. The results show that it is possible to recover the heterogeneity of the census tracts whenever the relations between the indicator variables and population occurrence are defined with criterion and the local particularities are taken into account.
The methodology developed for the municipality of Marabá was adapted to the Sustainable Forest District of BR-163 municipalities. As the area of interest was expanded, the cell size was enlarged, and the pattern of population distribution was obtained from the presence of communities. Data from fieldwork indicated an adequate fit between the population count predicted from the population surface and the total population for the communities along BR-163 highway
