Population Matters campaigns to stabilise population at a sustainable level through encouraging a culture shift towards smaller family sizes worldwide ("Pledge two or fewer") and improving funding for women's empowerment and family planning in lower income countries. Over the years, the organisation has run various campaigns, including supporting Caroline Lucas' Bill to make Personal, Social, Health and Economic education (PSHE) a statutory requirement in state-funded schools. Current campaign and lobbying activity focuses on biodiversity loss and challenging economic concerns regarding birth rate decline. It also informs the public on overpopulation and positive solutions through its communications, events and outreach activities. Finally, the charity undertakes and commissions research to examine some issues in depth, for example, publishing a report on the rise of coercive pronatalism, or exploring the feasibility of lower future population scenarios.
