Andries de JongPaper presented at the European Population Conference in the Hague, the Netherlands, 30 August - 3 September 1999.Abstract: This paper presents three Population and Labour Force Scenarios for the countries of the European Union. The scenarios project the population and the labour force by age and sex, both at the national and regional level (NUTS II classification). The national scenarios cover the period 1995-2050, the regional scenarios the period 1995-2025. The scenarios are based on an analysis of the determinants of population growth and labour force participation. The Baseline scenario aims to project the most likely development while the Low and High scenarios describe alternative developments in different economic and cultural contexts.
