Abstract
In a population projection apparatus, a memory stores past values of population changing components in each year within a first period. A computing circuit derives relational equations each representing a relationship between a change rate indicating a proportion relative to a population and an elapsed time period from the start of the first period, with respect to the population changing components. Next, the computing circuit calculates, using the relational equations, change rates of the population changing components in each year within a second period that starts from the year after the first period, and changes a part of the calculated change rates to change rates input as a scenario. Thereafter, the computing circuit calculates a population of each year within the second period on the basis of the population of the previous year and the change rates of the population changing components of that year.
