The document discusses the global aging population trend, noting that: - 10% of the global population was over 60 in 2005, projected to increase to 20% by 2050 - The population aged 80+ is the fastest growing segment and will increase from 72 million in 2005 to 394 million by 2050 - Increased life expectancy and decreased fertility are driving population aging - Europe currently has the oldest population, with those over 60 making up 20% in 2000 and projected to rise to 35% by 2050

1. Britain's ageing population

2. Global Introduction In 2005, 10% of the population was over the age of 60. In the developing world this was 8% of the population, and in the developed world 20%. This proportion is expected to increase to 20% by 2050. In 2005, 670 million people were aged 60 years and over. This is projected to increase to 1 billion by 2020 and to 2 billion by 2050. Causes increased life expectancy and the decline in fertility. Although ageing of the population has begun later in the less economically developed world, it is progressing at a faster rate than in the developed world. This is because the relative rates of decline in both fertility and mortality are much greater in developing than in developed countries.

3. The global average for life expectancy increased from 46 years in 1950 to 64 in 2000. It is projected to reach 74 years by 2050. During the same time period, the proportion of children is projected to fall from 33% to 20%. The population aged 80 and over numbered 72 million in 2005. This is the fastest-growing section (4.2% annually) of global population and is projected to increase to 394 million by 2050. Europe is the 'oldest' region in the world. Those aged 60 and over in 2000 formed 20% of the population and this is projected to rise to 35% by 2050. The % of old people and their rate of increase varies among countries. In 2005, those aged 60 and over ranged from + 25% in Japan, Italy and Germany to less than 5% in most tropical African countries and in the oil­rich countries of the middle east that attract young worker. By 2050, the range is expected to be even wider, from more than 40% in Japan, Slovenia and N. Korea to even less than 5% in the African countries of Swaziland and Liberia.

5. Europe In the EU, it has been predicted that by 2025: > there will be an increase in the number of people aged 60 and over - a further 37 million > one-third of its population will be pensioners - 111 million people > the working population (aged 20-59) will shrink by 13 million > the numbers of over-60s will outnumber the under­20s, for the first time in recorded history

8. Welcome to the ageing future By 2025, more than a third of the UK's population will be over 55. We're living longer and staying active until much later in life. So why the pessimism about the rise of Britain's ageing population? The underlying cause is that we are living longer and having fewer children - well below the replacement rate of 2.2 per woman - but the size of the baby boomer generation, who are just starting to retire, is accelerating the trend. By 2014, projections suggest, over-65-year-olds will overtake the under-16s. And by 2025, the number of over-60s will have passed the under-25s for the first time. Life expectancy at birth is increasing but an even more telling figure is the increase in life expectancy after 60. In the UK, a man who turned 60 in 1981 could expect to live another 16 years and a woman almost 21 years. By 2003 this had increased to 20 years for men and 23 for women; and according to official UK projections, by 2026 this will rise to almost 24 years for men and almost 27 for women.
