How do you help charities? We help charities in many ways, but most commonly in data advice, analysis of interventions and research to support advocacy and campaigns using national datasets. For charities that are looking to find out how cost-effective an intervention is, our volunteers use tools such as cost-benefit analysis, but have a range of skills that they can deploy. Our volunteers often spend time advising charities on data collection methods. In general, looking at the impact of one service or intervention is more straight-forward than conducting analysis of an organisation as a whole.
