Older people - UK
In 2007 there were 20.7 million people in Britain over the age of 50, 9.2 million of which were aged 50-65 and 11.5 million were over 65.
Life expectancy is currently increasing by over 2 years per decade meaning that the average life span increases by 5 hours a day.
Men over state pension age (65) have a life expectancy of 82 and women over SPA have a life expectancy of almost 85.
Currently, only 1/5 people do not survive to receive their state pension. The other 4/5 live on average for another 24 years, spending 1/3 of their lives in retirement.
In, 2007 the number of people over state pension age rose to 19% of the UK population, meanwhile the number of people under 16 fell to 18.9%. This means that, for the first time, those aged over 65 are proportionally higher in the population than those aged under-16.
The number of people aged over 65 is projected to grow from 9.9 million in 2008 to 12.2 million by 2018.
Currently 4 people of working age support each pensioner, but by 2035 it will be 2.5, and by 2050 only 2.
