World Population Day

World Population Day is observed every year on 11 July to draw global attention to population issues and their impact on health, rights and sustainable development. It provides an opportunity to discuss how many people are living on the planet, how quickly populations are growing or ageing, and whether people—especially women and adolescents—can exercise their right to make informed choices about if and when to have children.

History

The idea for World Population Day came from "Five Billion Day" on 11 July 1987, a symbolic date chosen to mark when the world’s population was estimated to have reached five billion. The rapid growth that followed raised questions about whether countries would be able to provide enough food, health care, education and jobs for their citizens.

In 1989, the Governing Council of the United Nations Development Programme (UNDP) recommended that 11 July be observed as World Population Day each year. Since then, the day has been used by the United Nations, national governments, NGOs and civil society organisations to highlight issues such as family planning, maternal health, gender-based violence, adolescent pregnancy and the rights of people to access reproductive health services.

The global population has continued to grow and passed 8 billion in 2022. However, trends vary widely: some countries face very high fertility and a "youth bulge", while others face low fertility and rapidly ageing populations. World Population Day encourages a balanced, rights-based conversation that goes beyond numbers to focus on people, choices and quality of life.

Why it matters

Population trends are closely linked with health, education, employment, housing, the environment and climate change. Rapid, unplanned population growth can put severe pressure on health systems, schools, water and sanitation, food supply and job markets, especially in low- and middle-income countries. When families are large and resources limited, it becomes harder to ensure that every child receives adequate nutrition, immunisation and education.

At the same time, the solution is not coercive population control, but respect for human rights—especially the rights of women and girls. Evidence from many countries shows that when women have access to education, decent work and voluntary, high‑quality family planning services, they tend to have fewer, healthier children. This improves maternal and newborn survival, reduces unsafe abortions and helps families escape poverty.

Key themes highlighted on World Population Day include access to modern contraception, informed consent, prevention of child marriage and adolescent pregnancy, and protection from gender-based violence. The day also draws attention to reproductive health services for men, including counselling on shared decision‑making in family planning and responsible fatherhood.

Key facts

In Bangladesh

In Bangladesh, World Population Day is particularly relevant because the country is one of the most densely populated in the world. Since independence, Bangladesh has made remarkable progress in reducing its total fertility rate—from around six children per woman in the 1970s to close to replacement level (around two children per woman) today. This achievement is often cited internationally as a success story in family planning and public health.

A key strength of Bangladesh’s approach has been its community‑based family planning programme. Trained female field workers visit households, especially in rural and low‑income urban areas, to provide counselling on birth spacing, distribute contraceptives, refer women to clinics for long‑acting methods, and link families with maternal and child health services. Government programmes, NGOs and development partners have worked together to expand access to contraception, antenatal care and safe delivery services.

Despite this progress, challenges remain. Many women—especially adolescents, women in hard‑to‑reach rural areas and urban slums—still face barriers to accessing accurate information and confidential, youth‑friendly services. Child marriage and early pregnancy are still common in some communities, increasing the risk of complications during childbirth and limiting girls’ education and employment opportunities. World Population Day is a reminder to strengthen efforts to delay marriage, keep girls in school, and ensure that both men and women can access safe, affordable family planning and reproductive health care.

Each year, Bangladesh observes World Population Day with rallies, media campaigns, seminars and community meetings organised by the Ministry of Health and Family Welfare, the Directorate General of Family Planning, NGOs and local government bodies. Messages focus on small, planned families; the health benefits of birth spacing; the importance of involving husbands in family planning decisions; and ensuring that no woman is forced or pressured into using—or not using—a contraceptive method.

For individuals and families, the day emphasises that choosing the number and spacing of children is a basic right and a key part of a healthy life. When couples are able to plan their families, mothers are healthier, babies are more likely to survive, and parents can invest more in each child’s nutrition, education and future.
