World Population Day

It took all of human history up to 1804 for the world’s population to reach 1 billion. But the next billion came only 100 years later, in 1927. After that, the rate of growth accelerated, 3 billion in 1959, 4 billion 1974, 5 billion 1987, 6 billion in 1999, and now well over 7 billion. World population reached 7 Billion on October 31, 2011. Figure mid-2019 the world population is now 7,710,900,800. We’re adding a billion population every 12 years. In mid-2019 the United States population is about 328,988,247 people.

Population growth is not even around the world. In Africa, for example, the current population of 1 billion and will increase to 3.6 billion by the end of the century. But, in Asia, yes, population will increase from its current 4.2 billion to 5.2 billion by 2050, but by the end of the century, it will fall to 4.6 billion.

Scientists figure in just two decades ahead, all the trends are indicating that we are going to need to be producing something like 40 percent more food, 40 percent more available freshwater, and actually about 50 percent more energy. Scientists say the planet’s population will peak at around 9.5 billion sometime between 2040 and 2060.
