World Population Day: Estimates and Results
The world commemorates World Population Day on July 11 each year, a day established by the United Nations General Assembly in 1989 in response to growing concern over the global population reaching five billion on July 11, 1987. Consequently, in December 1990, the UN General Assembly decided to mark this occasion to raise awareness of various population issues and their relationship with the environment, reaffirming the United Nations’ commitment to reproductive health rights, gender equality, and their necessity for achieving sustainable development worldwide. The year 1990 marked the first celebration of this day.
During the 20th anniversary of World Population Day, held on July 11, 2007, the global population stood at approximately 6.5 billion. Each year, nearly 83 million people are added to the world’s population. Projections indicate that the global population will reach 8.5 billion by 2030, 9.7 billion by 2050, and 10.9 billion by 2100.
The objective of this day is to foster close cooperation between the Population Division and the agencies, funds, programs, and bodies of the United Nations system in implementing the Programme of Action on population issues. The United Nations, governments, researchers, media outlets, and the public engage in periodic consultations regarding population estimates, their implications, and their connection to development indicators.
Recent decades have witnessed significant shifts in fertility rates and life expectancy. In the early 1970s, the average woman gave birth to 4.5 children; by 2015, this figure had declined to less than 2.5 children per woman. Simultaneously, global life expectancy rose from 64.6 years in the early 1990s to 72.6 years in 2019.
With this population growth come far-reaching consequences affecting economic development, employment opportunities, income distribution, poverty rates, and social protection systems. These impacts also extend to efforts to ensure universal access to essential services, including healthcare, education, housing, sanitation, water, food, and energy.
To meet individual needs in a more sustainable manner, policymakers must understand the size, geographic distribution, age structure, and generational composition of the world’s population. This occasion serves as an opportunity to educate the public about issues of concern and to mobilize the political will and resources necessary to address population challenges.
