We depend on our members and supporters. Your vital support will enable us to continue our campaigning, lobbying, education and research activities, and help us to move population up the public agenda. Members receive a welcome pack, our regular periodicals, merchandise, and invitations to take part in volunteering, group activities and our annual conference. Active members may apply to become guarantor members, which entitles them to a vote at our Annual General Meetings.

Why join?

Population numbers affect everyone’s well-being, other species and humanity’s future. 

  • We promote smaller families at home and abroad.
  • We publish research reports on the links between population numbers and resource security.
  • We develop materials on population and sustainability for teachers and others.
  • We lobby governments and international institutions by attending events and responding to consultations. We staff stalls, speak at fringe meetings and provide briefings.
  • We ask civil society to recognize that population size matters to the causes they promote.
  • We form local groups to raise awareness of population and sustainability, and support them with advice and materials.

We welcome your involvement in our activities. Education and making the general public aware of population is the most important thing you can do to help.  Whether by writing articles for our magazine or journal, organising film screenings, attending events, inviting one of our speakers to talk to an interest group, distributing leaflets or participating in stunts on key commemoration dates, these are all valuable ways you can help support our campaign. Whatever time and skills you have to offer, do get in touch. We make awards to volunteers who make a particularly significant contribution.

Another way to help is by joining one of our groups listed below. All actively contribute to our research, educational and advocacy activities on population and sustainability issues.
