An expert-based framework for probabilistic national population projections: the example of Austria.
This study recommends a probabilistic scenario approach for population projections. The benefits are better information, ease of adoption, and expert opinion on the mean and range of uncertainty. The study answers whether it matters if high and low variants cover 85% or 95% of the range. An assumption of piece-wise linear random paths may underestimate the variance of the resulting populatio...
Dreaded doomsday ageing consequences in, particularly European countries and Japan, a result of past protracted fertility decline, provides a pivotal lesson.
