What is the total number of people that have ever been alive?

Question

Roughly since the dawn of man.

Answer 1

Edit: Wow, I was wrong. According to this website, about 106 billion humans have lived on Earth. That's probably now depending on when the article was written.

"Back in the 1970s, someone wrote that 75 percent of all those ever born were living at the time. This much-quoted statistic dramatized the effect of the 20th-century population explosion, but it seems impossibly high. To get at a more plausible answer, we must have some idea when the modern human race began and what the birthrate and the total population were throughout history. Homo sapiens is thought to have appeared about 50,000 years ago. For almost all of the time since then, we can safely assume that few attempts were made to limit the number of births and that life was short, resulting in a young population and a high fertility--perhaps six to eight offspring per mother. By the Middle Ages, the birthrate is thought to have begun a long decline. From the 18th century onward records show that birthrates continued to fall in industrialized countries. Before the invention of agriculture, the global population was probably no more than 5 million to 10 million, kept low by the hunter-gatherer lifestyle. By A.D. 1 the population had risen to about 300 million, judging from fragmentary censuses in Rome, China, and the Mediterranean. Applying a high birthrate to that population, we can estimate a total 106 billion humans have been born. The 6.1 billion living at present therefore represent 5.7 percent of all who have lived. Rapid growth in developing countries has caused the global population to soar from just 1.6 billion in 1900, so the percentage currently alive compared with those ever born is actually rising."

Here's an article from a different website:

"There are a variety of myths on the Internet and circulated by word of mouth claiming that some extremely high percentage -- 25 to 50 to even 75 percent -- of all human beings who have ever been alive are living now. None of these estimates is correct.

Although it is impossible to accurately measure how many people have been alive, the Population Reference Bureau estimates that from 50,000 BCE (when homo sapiens first appears) through 1995, it is likely that more than 100 billion human beings have been born. Current world population makes up about 6 percent of all human beings who have ever been alive"

The Population Reference Bureau guestimates that at least 106,456,367,669 human beings have been born.

Answer 2

Well if one assumes the current world population (post-Flood)began about 6 thousand years ago, then if you take an integral of the curve of about 1940-1950 back, which would be about the proper amount of people prior to the people of today if the average life span today is about 55-65 years worldwide, this number is typically estimated as appx. 5 billion. This number is concluded based on the fact that technology and other things suppressed population growth for about 1000 years (3000BC) and the plague caused a dramatic drop in the middle ages.

The total population of living people today is between 6 and 7 billion. This totals appx. 11-12 billion years. Many people are going to use the common 100+ billion total derived today because the assumption according to evolutionists is man has been around between 100,000 and 2 million years. And the population steadied for much of the time prior to the historical era which causes a huge integral area prior to the modern period. Anyone who has done any form of simple population analysis for organisms understands that this is illogical and that right now humans are on the ascending J-curve of a population growth model.

This is why many contemporaries worry about a huge plague or other form of problem will cause the population to dramatically crash since a lack of resources is not a major problem for humans. That is why it is estimated we will overpass the population number that can be supported by current resources and cause a crah.

Answer 3

i'm notably particular it extremely isn't the case. i might might desire to hold out a little math to confirm that, however. How do you desire to define "human beings"? Our modern-day species is often considered to enlarge back approximately 2 hundred,000 years, however the variety might desire to be shorter, or lots longer, counting on the form you desire to define the gang. Addendum: enable's look at it this form. The Earth's inhabitants became approximately 450 million back whilst the Bubonic Plague hit back around 1400. So, there have been atleast a 0.33 of one thousand million human beings on earth each century considering the fact that then, and in all likelihood for relatively some centuries in the previous then. whether human beings lived 50 years on accepted back then, it extremely is a few billion people who die in keeping with century. whether the Earth's inhabitants became purely 50 million earlier to the 20 th century, that equals ten billion deaths over the final 10,000 years *on my own*. and you have have been given yet another one hundred ninety,000 years to function up in the previous that.

Answer 4

35 to 40 billion

Answer 5

As HELP said, the "guesstimate" IS 20 Billion, do the math.

We have all the population data going back for thousands of years, just look it up and add : )

Answer 6

I be;lieve it is approximately 20 billion

Answer 7

Hmmm... that is a hard one

Answer 8

ummmmmmmm..........................70 zillion
