10 of World's Most Populated Countries/Nations (UNFPA 2011)

World Population Day, which seeks to focus attention on the urgency and importance of population issues, was established by the Governing Council of the United Nations Development Programme in 1989. It was an outgrowth of the interest generated by the Day of Five Billion, which was observed on 11 July 1987. This year it marks the leadup to another milestone -- the World at 7 Billion.

Each year a number of UNFPA Country Offices and other organizations and institutions mark the day with a variety of activities to bring attention to population issues. UNFPA, which sponsors the observance, publishes posters and other advocacy materials for this purpose. 6,929,400,000 is the total approximation of world population as of July 7, 2011
