Numerous studies have demonstrated the pervasive effect of socioeconomic status on mortality and cause-specific mortality. More recently, a growing number of studies have indicated a widening of socioeconomic inequalities. It has therefore become crucially important to understand and model the mortality of a heterogeneous population. Recent developments in multi-population mortality have improved the modeling and forecast of subpopulations mortality inside a national population. But this new class of models has raised a number of questions, among which the issue of consistency between subnational and national forecasts. Hence, modeling population dynamics provide complementary insights on subpopulations evolution as well as on aggregated quantities.
