The United Nations expects world population to rise to more than 9 billion by 2050, and 11 billion by 2100.

What we do in the next 10 to 20 years will largely determine the scale of this increase, the future quality of human life on the planet and the prospects for survival of our fellow species.

Change will occur only if we take action. Here are simple steps you can take to help.

Support our campaigns

We campaign to promote the choice of having a smaller family, remove the obstacles that stop people making that choice, and ensure governments and other organisations are doing all they can to bring about a sustainable population. Add your voice to ours.


Become a member

We receive no government funding and rely on donations from our members to deliver our work. The most effective way to support us is to become a Population Matters member.


Have a small family

Choosing to have few or no children is the single biggest thing you can do to reduce your impact on the environment. 


Empower to Plan

Help deliver family planning to women in need by supporting one of our excellent Empower to Plan partner organisations.


Other actions you can take

Consume sustainably, limit your waste, slash your emissions... There are many other things you can do to help the planet.
