Presents information about fertility, mortality and migration, in Europe, to show possible future developments in population age structures and sizes.

Even as the 2013-2017 “migration crisis” is increasingly in the past, EU countries still struggle to come up with alternative solutions to foster safe, orderly, and regular migration pathways, Europeans continue to look in the rear-view mirror.This Report is an attempt to reverse the perspective, by taking a glimpse into the future of migration to Europe. What are the structural trends underlying migration flows to Europe, and how are they going to change over the next two decades? How does migration interact with specific policy fields, such as development, border management, and integration? And what are the policies and best practicies to manage migration in a more coherent and evidence-based way?

On the threshold of a new century the organisers of the European Population Conference 1999 (EPC99) in The Hague decided not only to highlight the population trends that Europe is facing today but also the changes in the 21 st century that are set to shape the future of Europe. They decided to focus on comparative issues, both in time and in space. In order to trace the degree of homogeneity and heterogeneity of European populations over time, converging and diverging population trends that are specific to contemporary and future Europe need to be explored. This is reflected in EPC99's motto: 'European Populations on the threshold of the new millennium; unity in diversity. ' Future demographic developments will be caused by specific economic, social and cultural conditions in Europe, and will, in turn, have a major influence on future economic and social conditions. To the extent that demographic trends differ across countries, separate countries may face different social and economic problems. As demographic trends tend to have long-lasting effects, it is important to assess the possible consequences of future demographic developments at an early stage. On the occasion of EPC99 , two of the organisers, Statistics Netherlands (SN) and the Netherlands Interdisciplinary Demographic Institute (NIDI), decided to produce a set of two population scenarios, showing the possible impact of converging and diverging population trends in the next century.

De nadruk wordt gelegd op het verband tusschen de wederopbouw en de richting waarin het bevolkingsvraagstuk zich in de komende decennia (vermoedelijk) zal ontwikkelen. De demografische factoren zullen, evenals in het verleden, in de nabije toekomst de maatschappelijke, economische en staatkundige constellatie ten zeerste beïnvloeden.
