People under the age of 25 are twice as likely to volunteer as people above that age, according to research by nfpSynergy.
The think tank's youth awareness monitor, a new bi-annual survey of 1,100 11 to 25-year-olds, found 41 per cent claim to volunteer. A previous nfpSynergy survey discovered 19 per cent of over-25s volunteer.
The study found that TV advertisements are the most common way young people learn about charity campaigns (69 per cent).
Sixty per cent said they learnt about charity campaigns from TV programmes, 46 per cent from print media and 41 per cent from charity shops.
"Something as well publicised as the Make Poverty History campaign has shown that young people are interested in the idealism that underpins it," said Joe Saxton, director of nfpSynergy. "Far from being 'born hoodies' as media reports suggest, they are keen to volunteer."
Ofcom's decision to ban the Make Poverty History 'click' advert threatened to reduce the number of young campaigners, Saxton added. "It's a strange notion that in today's world it is easier to advertise pornography than it is to advertise idealism," he said.
