Definition: Population scenarios (Eurostat)
Population projections carried out by Eurostat for all the Member States of the European Economic Area. These projections are comparable from country to country. Three scenarios are published: the variants HIGH and LOW are the two plausible extremes of demographic change, while the BASELINE scenario is the product of the "best hypotheses" which are comparable on an international level.
