The Demopaedia team will be present at the next International Population Conference in Busan.
If you attend the conference, please, come to our oral communication which will be held on Tuesday August 27, from 15:30 to 17:00 (Bexco, room 213). The new Korean dictionary will also be presented in a side meeting organized by the Planned Population Federation of Korea (PPFK) on "Population Issues & Official development assistance" (open to all) at 19:00 (Bexco, room 110).

A demographic model ^{1} consists of a theoretical construct representing the evolution of a population (of individuals, couples, families, households, etc.) and its structure on the basis of its initial state and the effect of various demographic variables (such as fertility, fecundability, mortality, etc.). In a static model ^{2}, these variables remain constant; in a dynamic model ^{3}, they are allowed to change over time. A further distinction is made between deterministic models ^{4} which assign functional relations between definite values of the variables, as if the studied population were infinitely large, and stochastic models ^{5} or probabilistic models ^{5} which consider the probability of various events occurring to individuals over the duration of the process under study. The model may be set out in mathematical formulas or take the form of a simulation ^{6} where specific values of the variables are included in a system of relations. Macrosimulations ^{7} may for example involve population projections made by the component method (720-5). In microsimulations ^{8}, events are made to occur randomly to individuals or groups over time according to sets of probabilities assigned to the variables in the model.
- 1. The word is also used as an adjective in such expressions as model tables.
