The world saw 3 billion by 1959 and 5 billion by 1987. As of 2019, the total fertility rate for the world was roughly 2.5, down from 2.8 in 2002 and 5.0 in 1965, but still at a rate that allows population growth..

"bayesTFR: An R Package for Probabilistic Projections of the Total Fertility Rate". According to the U.N. Department of Economic and Social Affairs, the world's population has been rising at a rate of roughly 83 million people every year, and the trend is expected to continue, even though fertility rates have been dropping in almost all regions of the world. That's because the world's overall fertility rate still exceeds the rate of zero population growth. All middle and high school students are eligible to enter. Gerhard K. Heilig, Thomas Buettner, Nan Li, Patrick Gerland, Leontine Alkema, Jennifer Chunn, Adrian E. Raftery. (2011). The world population has grown tremendously over the past 2,000 years.

In contrast, the fertility rate in many developed countries was below replacement value (more loss of people than those born to replace them). In the fall of 2011, world population surpassed 7 billion and as a citizen of the earth, it’s important to understand how we reached this milestone, analyze the impact of our choices, and realize that our decisions can and will impact the future.

(2010). While data is collected on population growth, it is difficult for even sustainability professionals to understand what will happen on a global scale when the world's population reaches 10 or 15 billion people. Our population is expected to grow to over 9 billion by 2050, yet the ability of our environment to provide space, food, and energy are limited. The 47 least developed countries are expected to see their collective population nearly double from roughly one billion to 1.9 billion by 2050. That's thanks to a fertility rate of 4.3 per woman.
