Population Matters is a charity that addresses population numbers and their effects on environmental sustainability. We see population growth as a major contributor to pollution, climate change, dwindling natural resources and many other problems. To address these problems, we promote improved family planning and better sex education, both of which lead to smaller and thus more sustainable families.

Population Matters, which was founded in 1991 in the United Kingdom, now is an international organization that has thousands of members across dozens of countries.

Our vision is of a sustainable future with decent living standards, a healthy environment and a stable population size.

Our mission is to promote smaller families throughout the world in order to reduce human population numbers to a sustainable level. We in addition encourage mindful consumption.

Our goals include universal access to family planning services, an end to discrimination against women and a global convergence in living standards.

All of our activities are guided by our values.

Our income comes primarily from our many individual members. Significant contributions are listed in our annual reports.

The people associated with our organization include our patrons, advisory council, board, team of staff and volunteers and members.

Our policies are intended to affirm our responsibilities to others, improve our performance and minimize risk.
