As the theme of this year’s World Population Day reminds us, investing in data collection is important to understanding problems, tailoring solutions, and driving progress. So is finance. I urge countries to make the most of the Summit of the Future this year to unleash affordable capital for sustainable development.”

To Leave No One Behind, Count Everyone

Over the past three decades, societies around the world have made remarkable progress in improving population data gathering, analysis, and use. New population figures, disaggregated by age, ethnicity, gender, and other factors, now reflect the diversity of our societies more accurately.

These advancements have significantly enhanced the delivery of health care globally, leading to substantial improvements in sexual and reproductive health and the ability to exercise rights and choices. Increasingly, new technologies are enabling more detailed and timely measurement of people's experiences than ever before.

However, the most marginalized communities remain underrepresented in data, profoundly affecting their lives and well-being.

World Population Day 2024 is a moment to ask who is still going uncounted and why – and what this costs individuals, societies, and our global efforts to leave no one behind. It is also a moment for all of us to commit to doing more to ensure that our data systems capture the full range of human diversity so that everyone is seen, can exercise their human rights and can reach their full potential. 

To realize the rights and choices of those on the margins of our societies, we must count them – because everyone counts. Our rich human tapestry is only as strong as its weakest thread. When data and other systems work for those on the margins, they work for everyone. This is how we accelerate progress for all.

 

 

World Population Trends

It took hundreds of thousands of years for the world population to grow to 1 billion – then in just another 200 years or so, it grew sevenfold. In 2011, the global population reached the 7 billion mark, it stands at almost 7.9 billion in 2021, and it's expected to grow to around 8.5 billion in 2030, 9.7 billion in 2050, and 10.9 billion in 2100.

This dramatic growth has been driven largely by increasing numbers of people surviving to reproductive age, and has been accompanied by major changes in fertility rates, increasing urbanization and accelerating migration. These trends will have far-reaching implications for generations to come.

The recent past has seen enormous changes in  and . In the early 1970s,  4.5 children each; by 2015, total fertility for the world had fallen to below 2.5 children per woman. Meanwhile, average  have risen, from 64.6 years in the early 1990s to  72.6 years in 2019.

In addition, the world is seeing high levels of  and accelerating migration. 2007 was the first year in which more people lived in , and by 2050 about 66 per cent of the world population will be living in cities.

These megatrends have far-reaching implications. They affect economic development, employment, income distribution, poverty and social protections. They also affect efforts to ensure universal access to health care, education, housing, sanitation, water, food and energy. To more sustainably address the needs of individuals, policymakers must understand how many people are living on the planet, where they are, how old they are, and how many people will come after them.

  • More than of women around the world cannot make decisions on sexual and reproductive health and reproductive rights.
  • As few as across low- and middle income countries are realizing their desired fertility.
  • A woman dies every two minutes due to pregnancy or childbirth (and in conflict settings, the number of deaths is twice as high).
  • Nearly one third of women have experienced intimate partner violence, non-partner sexual violence or both.
  • Just six countries have 50 per cent or more women in parliament.
  • More than two thirds of the 800 million people globally who cannot read are women.

The dramatic growth of world’s population has been driven largely by increasing numbers of people surviving to reproductive age, and has been accompanied by major changes in fertility rates, increasing urbanization and accelerating migration. These trends will have far-reaching implications for generations to come. The United Nations system has long been involved in addressing these complex and interrelated issues – notably, through the work of the and the UN Population Division of the Department of Economic and Social Affairs.

The State of World Population 2024: Interwoven Lives, Threads of Hope

Titled?“Interwoven Lives, Threads of Hope: Ending inequalities in sexual and reproductive health and rights”, the 2024 edition of United Nations Population Fund’s () flagship report "" underscores the ongoing impact of racism, sexism, and other forms of discrimination in obstructing significant progress in sexual and reproductive health for women and girls. The data are damning. Women and girls who are poor, belong to ethnic, racial, and indigenous minority groups, or are trapped in conflict settings, are more likely to die due to lack of access to timely health care. The report calls for global action to dismantle unjust and discriminatory structures that prevent millions from realizing their full rights and potential.

International days and weeks are occasions to educate the public on issues of concern, to mobilize political will and resources to address global problems, and to celebrate and reinforce achievements of humanity. The existence of international days predates the establishment of the United Nations, but the UN has embraced them as a powerful advocacy tool. We also mark other UN observances.
