History of World Population Day

World Population Day was established in 1989 by the United Nations Development Programme (UNDP) following the milestone of the global population surpassing five billion people in 1987.

The UNDP focused on supporting the needs of a growing population and created this observance to raise awareness and promote action on population-related issues.

To address the urgency of population-related challenges, the United Nations Development Programme (UNDP) played a proactive role in establishing World Population Day in 1989.

As an essential department of the United Nations, the UNDP is committed to supporting and anticipating the needs of an expanding global population.

Since its establishment, World Population Day has grown into a widely acknowledged and respected observance on a global scale. It has gained prominence and international recognition as a platform dedicated to increasing awareness about a range of population-related issues.

World Population Day has evolved to address various important issues beyond population growth, including gender equality, human rights, poverty alleviation, and family planning. By tackling these challenges, the observance aims to promote sustainable development globally.

The day brings awareness to several issues, namely:

  • The rapid growth in population number has brought several new challenges.
  • The importance of making birth control and family planning available to those who don't have access to it. 
  • The need to control poverty and give better maternal health care to mothers worldwide. 

Why World Population Day is Important 

Human overpopulation strains the environment and poses a global challenge. While there are enough natural resources for everyone, the uneven distribution of the world's population hinders access to vital resources like food, water, and clean air, particularly in densely populated countries.

Overpopulation can be caused by an uncontrolled birth rate, increased immigration, and declining mortality rates. If the population rises to a number that is too unsustainable for the planet this could result in global warming, ecological collapse, and a depletion of resources that could cause mass starvation. 

Every year, it is estimated that the world's population grows by 83 million people, and at the same time, life expectancy keeps growing, due to the developments in health care. 

World Population Day is crucial as it brings attention to the interconnected challenges linked to population growth. By highlighting these issues, it urges governments, organizations, and individuals to take concrete actions for sustainable development and global well-being.

Through awareness campaigns, seminars, and NGO collaborations, World Population Day fosters dialogue and generates innovative solutions. It advocates for empowering individuals, protecting human rights, improving healthcare access, and promoting sustainable development in the face of a growing population.

What to do for World Population Day

There are many things you can do to observe and make the most of World Population Day:

  • Many organizations will have open activities such as seminars and information sessions, so the public can get information about the issues the world's population currently faces. 
  • Spend time today doing research of your own and looking into the problems of overpopulation to know what to do to help. 
  • Donate to one of the many NGOs and nonprofits that educate young people about contraception and family planning, or those that aid people in getting out of poverty. There are also organizations whose aim is to help refugees that have had to leave their homes for a new country. Any contribution you can make to these places is a great help in fighting overpopulation.
