These operators will generate a final value related to the potential of population occurrence provided by
the indicator variables interactions, for each grid cell, composing the adjacent surface model.
Finally, to disaggregate population from census tracts to cells, the total population count had to be
redistributed taking only the valid cells into account. Each grid cell had a potential of population occurrence
assigned from the operators between indicator variables. As census tracts are represented by several cells, the
population count for each cell was distributed as follows:
