             When we talk about world population growth statistics, we get into very large numbers with many confusing zeroes at the end. While lots of 0′s may bring back fond memories of our days of test scores and playing hooky from school, they do nothing to help us understand a factual sentence like: “The earth’s population is projected to rise from 6,400,000,000 in 2004 to 8,900,000,000 in 2050.

   That means we will likely increase world population by 2.5 billion people in the next half-century, but how do we put such a large number in context to make it easier to grasp? Does population growth just mean a few more people at the next block party, or will the teeming masses start falling off the edge of whatever cliff they’re closest to?

In this article, we’ll try to make sense of world population growth statistics, and then we’ll discuss why this increase in global population is significant.

 

WORLD POPULATION GROWTH —
THE STATISTICS AND TRENDS IN CONTEXTvvv

For simplicity’s sake, we’ll assume the population increase between now and 2050 will be linear. (Experts predicts that population growth will be faster in the early part of the period than in the later part, but for our purposes, working with an average increase will be fine.) Remember, we’re talking about the NET population growth—the number of new people born minus the number who die.

If we convert the total population growth of 2.5 billion for the first half of the 21st century to an annual rate of growth, we can expect 54 million additional people per year to occupy the planet. That large a number still seems pretty hard to relate to, though, so if we take it down to a per-day figure—which would be 149,000 net additional people per day—it’s

more understandable because we can compare it to figures we’re familiar with. For instance, 149,000 is two or three football stadiums worth of people (depending on the stadium capacity). Maybe that doesn’t seem like so many people at first, but remember how shocked we were when we were told about the death toll from the December 2004 Asian tsunami—several hundred thousand people died. Yet today we’re adding that many new people to the planet’s population every two days.

So, should we be cold, calculating statisticians who see that a high number of deaths from a natural disaster or, say, the one million people who die each year from malaria don’t matter because we’ve got so many new humans coming down the population-growth conveyor belt anyway? No, of course not. One of our top goals as a society should be to reduce and eliminate suffering wherever and whenever possible.

Does this leave us with the seemingly conflicting goals of keeping humanity’s numbers at a reasonable (sustainable) level vs. not wanting people to suffer and die?

Rate of Increase in World Population

          In our existence for the last 52,000 years on this planet Earth, there have been a total of about 106.billion people. Every year we add almost 78 million people to the world population and are rapidly consuming its resources.

In the year 1 AD we were only 300 million and our population was growing slowly at 0.5% per year. At the start of 1980 the world population was 4.4 billion but in 20 years we added over 1.6 billion people and the population was 6 billion. By 2015 it is predicted we will be more than 7 billion. A British Physicist estimated this alarming rise and predicted our current growth as follows-

‘At the current rate it would take only about 50 years to populate Venus, Mercury, Mars, the moon, and the moons of Jupiter and Saturn to same population density as Earth. . . It would take only about 200 years to fill [the remaining planets] “Earth-full.” . . . What then? .’   - J. H. Fremlin

      Some 43 countries have populations that are stable or declining slowly. A large group of countries has reduced fertility to the replacement level or just below. They are headed for population stability after young people move through their reproductive years. Included in this group are China and the United States. A third group is projected to more than double their populations by 2050. UN projections show growth under three assumptions about fertility levels. The medium projection has world population reaching 9.2 billion by 2050. The high one 10.8 billion. The low projection, which assumes fertility to 1.6 children has population peaking at just under 8 billion in 2041 and then declining. If the goal is to eradicate poverty, hunger, and illiteracy, we have little choice but to strive for the lower projection.

Prices for oral contraceptives are doubling and tripling at student health centers, the result of a change in the Medicaid rebate law that ends an incentive for drug companies to provide discounts to colleges.

 

Women are paying about $22 per month for prescriptions that cost $10 a few months ago. About 39% of undergraduate women use oral contraceptives. The discounts to colleges mean drug manufacturers have to pay more to participate in Medicaid and as a result fewer companies are willing to offer discounts.

“World population”!

Whats World Population?

                The world population is the total number of living humans on Earth at a given time. As of February 2009, the world’s population is estimated to be about 6.76 billion.^[1] According to population projections, this figure continues to grow. the 2008 rate of growth has almost halved since its peak of 2.2% per year, which was reached in 1963. World births have levelled off at about 137-million-per-year, since their peak at 163-million in the late 1990′s, and are expected to remain constant. However, deaths are only around 56 million per year, and are expected to increase to 90 million by the year 2050. Since births outnumber deaths, the world’s population is expected to reach about 9 billion by the year 2040.^[2][3]
