World Population Day

Thursday, July 11 is World Population Day. This is a special day that was first observed in 1989 to recognize the number of people living in the world. According to the U.S. Census Bureau’s International Data Base, the world population reached 7.5 billion just last year, on June 13. The population is projected to reach 8 billion in 2025.

The World Population Clock is a real-time counter that helps illustrate how quickly the population of the world is growing. Of course, these numbers are estimates and cannot be precisely accurate.

In the United States alone, there are some interesting population statistics:

  • 1 birth every 8 seconds
  • 1 death every 12 seconds
  • 1 migrant enters the U.S. every 34 seconds

All of the figures above translate to a population net gain of one person every 14 seconds.

Knowing that the world population is at nearly 8 billion, one might wonder how the United States compares with other countries in population. The countries with the highest population are:

  • China—1.3 billion +
  • India—1.3 billion +
  • USA—331 million
  • Indonesia—264 million
  • Pakistan—210 million
