New data from the British Market Research Bureau has shown that since 2000 there has been a gradual increase in the amount of money given by 11 to 19-year-olds, from £4.28m to £4.8m.
Russell Budden, a research consultant, said: "The impact of celebrities associating themselves with charities appears to have been successful."
The statistics show fans of U2 or Coldplay are 59 per cent more likely than the average youngster to have given to aid charities.
Lindsay Boswell, chief executive at the Institute of Fundraising, said the survey was great news but also urged caution, saying charities must consider the "reputational risk of working with celebrities". He added that the growing generosity of young people could also be due to the citizenship curriculum and the work of Giving Nation.
