Despite enormous gains in the wellbeing and economic circumstances of hundreds of millions of people, 10% of the world's population still live on less than $2 a day. High population growth traps individuals, communities and even entire countries in poverty. Achieving sustainable population levels, locally and globally, helps people achieve the dignity and standard of living we all deserve.
“ We cannot confront the massive challenges of poverty, hunger, disease and environmental destruction unless we address issues of population and reproductive health.”
– Thoraya Ahmed Obaid, UN Under-Secretary-General 2000-2010
Empowering, choice-based population solutions are key to achieving the decent quality of life for all and healthy environment envisioned by the UN's Sustainable Development Goals.
While billions enjoy an affluent style, more than a tenth of the world’s population live in extreme poverty today. Poverty is not a consequence of limited global resources, but political and economic injustice. However, the poorest people are almost always at greatest risk from environmental damage, climate change and competition for resources. The effects of unsustainable population hit the poorest first, and hardest.
The world's poorest countries tend to have the largest family sizes and fertility rates. When people have no economic security and cannot rely on their government and a social safety net, they often have children to ensure they will be looked after when they are older. Where child mortality is high, there is an even greater impetus to have more children. Those circumstances can lead in turn to a culture which values high family size.
This understandable human impulse can contribute to a vicious cycle. Poor families with large numbers of dependent children may perceive the need to take children out of education early, or marry off their daughers young. They will also often live in deprived communities where access to modern family planning is limited. All these factors combine to keep family sizes high, perpetuating the cycle.
"My statement that ‘development is the best contraceptive’ became widely known and oft quoted. 20 years later I am inclined to reverse this, and my position now is that ‘contraception is the best development’.”
– Karan Singh, Indian politician
What applies to families, applies also to nations. In poorer countries, providing jobs, infrastructure, health services and education to a constantly growing population can be an impossible task. In the worst cases, even food can be impossible to supply. In countries with very high population growth, huge numbers of dependent children in comparison to economically productive adults create a further burden. In sub-Saharan Africa, the median age of the entire population is just 19 years old. In Niger, the country with the world's highest fertility rate, the median age is just 15.3 years.
“The high population is exerting a lot of pressure on our economy. As a country we have made tremendous gains over the years but the impact is not reflected on our economy because the gains have been dissipated by population growth”
– Goodall Gondwe, minister of Finance, Malawi, 2017
In contrast, countries which have been successful in bringing down their fertility rates, have moved out of poverty more quickly.
While people living in poverty make a minuscule impact on global environmental problems such as climate change, they can have a devastating impact on their local environment. Soils may be eroded in an attempt to increase crop yields, fish stocks decimated to provide food and local forests razed for timber and firewood. These actions, along with increasing conflict between humans and wildlife and hunting of animals for food can have a significant impact on biodiversity.
Of course, where people are dependent on the local environment for subsistence, this damage contributes to further poverty. People with limited options are often well aware that their actions threaten their own future, but have no choice other than to continue to over-exploit their local resources.
Environmental damage can have wider impacts. For instance, in places where there is no water supply and no refuse collection, people are obliged to use and discard plastic packaging or bottles, sometimes in waterways, contributing to plastic pollution in the oceans. The perception that poverty equates to a low environmental footprint does not hold true in many circumstances.

The recipe for ending population growth is positive and simple, and also leads to a better quality of life for all:
If all of these methods are used in combination, they are most effective, and have secured dramatic reductions in fertility rates in many countries.
