Update 2.15pm: When it comes to registered charities, a new report shows that 300,000 people volunteer every year but only 17% of them are under the age of 24.
Young people are being urged to volunteer more in the charity sector.
The most popular age to volunteer is from age 45 to 64.
Alan Gray from consultancy firm Indecon, which wrote the report, says young people do not volunteer as much as their elders.
"What would be good is if mechanisms and supports could be put in place to encourage more young people to come into the charity sector."
