Population ageing has been occurring in many countries within Europe, North America and elsewhere for a number of decades. However, recently the pace, size and global reach of such ageing has begun to be recognised, and the wider implications assessed. Population ageing poses a key policy challenge for social security and health care systems across the globe. Different governments will come to these considerations carrying with them contrasting demographic profiles, welfare regimes and institutional structures, and cultural systems. The future success of societies in their efforts to accommodate such demographic change will, to a large extent, rest with the capacity of social security and health care institutions to adapt to an ageing world.
