July 11 is World Population Day (WPD), an annual event launched in 1989 by the Governing Council of the United National Development Programme.

World Population Day

The annual event was inspired by Five Billion Day - July 11, 1987 - the day when the world’s population reached five billion. WPD raises awareness about various issues that affect us all. Each year, governments, businesses, organizations and individuals from all over the world will observe the event by attending workshops, rallies and a variety of activities in honor of WPD. With a different theme for each year, the 2014 theme is Investing in Young People.

Population Facts

  • In 1950, the world population was 2.5 billion. Today, more than 7 billion people inhabit the earth.
  • The world population increases by 2.3 people per second.
  • 6 countries account for half of the world’s population - United States, Brazil, China, India, Pakistan and Indonesia.
  • The U.S. population is currently over 318 million – up from 316 million in 2013.
  • California has the largest population – over 38 million.
  • In the United States, one person dies every 13 seconds and one birth happens every eight seconds.

As people live longer and healthier lives, the population continues to grow and challenges also increase. Hunger-related diseases, food and water shortages, insufficient sanitation, overcrowding, diminished air quality and environmental issues are just a few of the issues associated with overpopulation.

The World Clock website provides information ranging from the earth’s temperature and total Internet users to infectious diseases and extinct species. According to the site, over 70 million people are born and 29 million die each year. Over 14,000 species are now extinct.

The Population Research Institute is an international, non-profit group which helps to “end coercive population control and fight the myth of overpopulation which fuels it.”

July 11 is also 7-Eleven Day and National Cheer Up the Lonely Day.
