Population Matters is a membership charity that addresses population size and its effect on environmental sustainability. We see population growth as a major contributor to environmental degradation, resource depletion and other problems. To address these, we conduct research, inform the public and advocate improved family planning, better sex education and women’s empowerment, which together yield smaller and thus more sustainable families.

  • We were founded in 1991 in the United Kingdom and we are now an international organization with 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.
