World Population Day is an annual event to be celebrated on 11 July, with the aim of raising awareness of population issues. This day was first announced by the Governing Council of the United Nations Development Program (UNDP) in 1989. This day was inspired on 11 July 1987, with a world population of approximately 5 billion.

This year's International Population Day is intended to give universal attention to the unfinished business of the International Conference on Population and Development in 1994, in which 179 States recognized the fact that reproductive health and gender equality are essential for sustainable development.

On World Population Day, activists from all over the world call on leaders, policy makers, grassroots organizers and others to help make reproductive health and rights a reality for all.

"The Sustainable Development Plan for 2030 represents the world's way to a better future for all on a healthy planet," said UN Secretary-General Antonio Guterich on the World Population Day, recognizing that the task is closely linked to demographic trends including population growth and aging Migration and urbanization ". Explaining that this year's World Population Day calls for universal attention to the unfinished business of the Cairo Conference on Population and Development.

"While the world's overall population is still growing, this growth is not happening at a single pace: for many of the world's least developed countries, the challenges to sustainable development are compounded by their rapid population growth and vulnerability to climate change Other countries face the challenge of population aging, including the need to promote active health aging and adequate social protection As global urbanization continues, with 68 per cent of the world's population expected to live in urban areas by 2050, sustainable development and change Climate will increasingly depend On the successful management of urban growth ".

The Governing Council of the United Nations Development Program (UNDP) announced World Population Day to focus attention on the importance of population issues in 1989, due to the concern that the world population reached 5 billion on 11 July 1987.

By its resolution 45/216 of December 1990, the General Assembly decided to continue to commemorate that occasion in order to promote awareness of population issues and their relationship to the environment and development.

Current estimates indicate that nearly 83 million people are added to the world's population each year. Even assuming fertility levels continue to decline, the world's population is projected to reach 8.6 billion in 2030, 9.8 billion in 2050, and 11.2 billion in 2100, according to projections of medium variables.
