The document discusses trends in the UK population including aging, immigration, and regional shifts. Some key points: - The proportion of over-60s is expected to rise significantly, increasing the dependency ratio and challenging the economy. - Immigration has helped offset population aging but its future impact is uncertain. - Younger workers have moved to southern and eastern regions while older residents settle in coastal and rural areas. - The upcoming decades will see the large "baby boom" generation retire, placing greater burden on a smaller working-age population to support them. Careful planning is needed to address this challenge.
