A population calculation system includes: an acquisition module acquiring the number of counted people who are counted as samples in a count area containing a target area; a first calculation module calculating population in the count area on the basis of the number of counted people acquired and a scaling factor for determining the population in the count area on the basis of the number of counted people; a second calculation module calculating population in the target area on the basis of the population in the count area thus calculated; a quantization module concealing the population in the count area or the population in the target area on the basis of a class interval that is a product of concealment reference that is a reference value of a minimum summation unit and the scaling factor in calculation processing; and an output module outputting concealed population in the target area. |
