Never before had population grown so rapidly - in 1950, five years after the founding of the United Nations, world population was estimated at around 2.6 billion people. It reached 5 billion in 1987 and 6 billion in 1999. In October 2011, the global population was estimated to be 7 billion. A global movement "7 Billion Actions" was launched to mark this milestone. The world’s population is expected to increase by 2 billion persons in the next 30 years, from 7.7 billion currently to 9.7 billion in 2050 and could peak at nearly 11 billion around 2100.
Every day, hundreds of thousands of girls around the world are harmed physically or psychologically, with the full knowledge and consent of their families, friends and communities. And without urgent action, the situation is likely to worsen. These are the findings of UNFPA’s flagship 2020 State of World Population report. The report examines the origin and extent of harmful practices around the world, and what must be done to stop them.
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.
