The number of Britons over 50 has risen by 45% during the past 50 years and the age group seems to be better off, government figures suggest.
Saga said over 50s were enthusiastic users of technology
An Office of National Statistics study found current pensioners' net incomes had risen faster than average workers' - by 28% between 1995/96 and 2003/04.
It said in 2003, there were 20 million people aged 50 and over in the UK, up from 13.8 million in 1951.
"Focus on Older People" was based on the 2001 census and other studies.

The Office of National Statistics said generous company pensions and benefits had led to the rise in average earnings for those aged over 50.
But it said over a fifth of pensioners lived below the poverty line.
It found employment rates for Britons in their 50s had risen by seven percentage points for both men and women between 1995 and 2004 and that more older people were learning new skills.
Ten per cent of men over 80 use the internet, with one in three having a mobile phone.
Angela Horsman from the Saga Group, which caters for those over 50, told the BBC: "They may be a little slower to take up the technology, but once they actually do embrace it, they're really enthusiastic users.
"They see it as something that can make their life easier and they want to keep up with the times when it comes to technology."
The study also found that men aged 75 or above were most likely to drink at least five days a week but least likely to do so to excess.
