    World (Over)Population

    MANY years ago, perhaps 25 or 30, I read the following statistic: "Out of every TWENTY people who have EVER lived, one is alive today."

    This seems unbelievable at first glance, but given statistics of the growth of world population, and following those stats in reverse, I do not doubt that it was true at that time.

    Now, my question is this: Does anyone know what the current stats are in this regard?

    Now 1 out of 18, 15, ???

    I've done a *rough* estimate from the figures on This Page and I make it about seven out of every twenty.

    FourPart referred to what I have always believed to be true, in that "There are more people alive today, than have ever died"
    Is that true, because it doesn't agree with Bryns estimate.......does it ? Mathematics makes my brain hurt.
    I thought I knew more than this until I opened my mouth

    Very dramatic statements, and I am sure there are statisticians that can offer some interesting demonstrations to back up such claims.
    I can point out that there are now nearly three times as many people alive on the planet as there were when most of the regulars here were born.

    However, according to the Population Reference Bureau
    Something over 100 Billion people have set foot on the planet over the millennia.
    We're not there, yet.

    That's the figure I was trying to get to using the estimates of world population over the past hundred thousand years.

    With the best will in the world I can only just get the numbers to just over forty billion dead and that's not taking proper allowance for those in the latter half of the twentieth century who are still alive - call it fifty billion all told which gives us one in seven still alive.

    I was thinking along the lines of Binary counting, with each bit being the population of a generation

    I read this just last month: "The farmers of the world will have to grow as much food in the next fifty years, to feed the population, as they have in the last five thousand."

    Scary figures, but I can well believe it.

    The Population Bomb

    It warned of the mass starvation of humans in the 1970s and 1980s due to overpopulation, as well as other major societal upheavals
    Now we have "Climate Change" fear.

    Hmm,

    Just thinking. Maybe a reduction in the population of people is the answer?

    OK, One-child policy

    Well, I don't know how well that will go over in free countries.
