The proportion of adults who volunteer regularly has increased by eight percentage points since 2010/11, new government data shows.
Figures from the most recent Community Life survey 2012/13, which cover August 2012 to April 2013 and were published on Friday, shows that 49 per cent of adults carried out some form of volunteering at least once a month.
In 2010/11, the final year of the Citizenship Survey, the figure was 41 per cent.
The Community Life survey is based on 6,600 interviews with adults in England. It replaces the larger Citizenship Survey, which previously collected data on social action including volunteering, charitable giving, community engagement and wellbeing from about 9,000 people over the course of a year
The Cabinet Office said in a statement that there had been "a significant increase following London 2012" in the number of people volunteering.
The publication of the results coincided with Friday’s Go Local event, open to all London 2012 volunteers, which is being co-hosted by Olympic and Paralympic legacy charity Join In and Team London, the Mayor of London’s volunteering programme.
The event, in the Queen Elizabeth Olympic Park in east London, featured performances by the comedian Eddie Izzard and the band McFly.It came before the Join In Summer event, which will run from 27 July to 9 September and will involve sports clubs and community groups holding more than 10,000 events to encourage volunteering, according to Join In.
