The addition of 80 million people each year to an already overcrowded globe is exacerbating the problems of pollution, desertification, underemployment, epidemics, and famine.

Isn't that a bit subjective?

---

Perhaps it would be more accurate to show where in the globe can be classed as being overcrowded, as it is not a widely held opinion that the world in itself is overcrowded. There are areas in the world where no people can live due to climate, but there is no reason to suggest that future technology will not allow people to live there. With this in mind, it is important to show that overcrowding affects the economies of those places that *are* overcrowded. —Preceding unsigned comment added by 84.66.251.247 (talk • contribs) 22:37, 28 May 2005

There is more to "crowding" than placing a human (or two or twenty) on every human-sized parcel of land. The area around Lake Chad doesn't have nearly as high of population density as Bangladesh, but the lake is still disappearing due primarily to too many homo sapiens running around.

[edit] GDP

GDP numbers (PPP), (currency), during 2003. $50.4 trillion, per person that's $8000(50.4/0.0063).

Per capita GDP growth rates: [1] set the 1950 PPP GDP at $6.8 trillion, [2] set the population at 2,555,360,972, that makes the per capita GDP $2,661 in 1950, compared with 2003 there's a 201% increase, that's 2.1% a year (2661*x^53=8000).

Since 1993s $6,599 (36.5/5,531,014,635) it's 1.9% a year (6599*1.9^10=8000). As a comparison, the IMF database put the PPP GDP at $30 trillion during 1993 ([3]), that's $5,424 per person (30/5.531). That's a 4.0% per year growth rate (5424*1.04^10=8000) - Jerryseinfeld 00:38, 4 Dec 2004 (UTC)

[edit] China

This article says that China is the second largest economy in the world, but the economy of China article says its the sixth. huh? The bellman 14:41, 2005 Mar 24 (UTC)

[edit] More China

Yes, I noticed the discrepency about China, too. Wikipedia's article on largest economies, http://en.wikipedia.org/wiki/List_of_world%27s_largest_economies

lists China as the sixth largest, while this article says it is second. This may be due to difficulty in measuring China's economy. Does anyone have a source we can quote? Carax 8 July 2005 02:51 (UTC)


[edit] Funny precision

Some values are given with lots of significant digits, which have no sense. There is no sense in "Population (midyear) 6,451,058,790", not only because it's changing every second, but because of lack of reliable statistics. I propose to round everything to 3 or less digits. --MvR 14:51, 24 November 2005 (UTC)

  • I second that proposal, because it is totally absurd and probably pulled out of a hat. I, in fact, would go so far as to put the world's population at two significant digits because that's probably the granularity of the statistics. Also, 6.50 billion gets a little awkward unless you're reading a scientific report, which this is not. (Similar arguments for other numbers) IMacWin95 22:30, 30 June 2006 (UTC)
  • (Sorry for another recent update) Following a link bed, I get to http://www.census.gov/ipc/www/popwnote.html, which clearly states that the estimate is "not intended to imply that the population of the world is known to the last person. Rather, the clock is our [the site's] estimate of the world population size and an indication of how fast it is growing." The clock is also updated at about only 5-minute intervals, with changes in the thousands place, so any data "more accurate" than one million is probably incorrect...

[edit] PPP and GDP per capita seem off

The listed per capita PPP is $9,300, but the listed global PPP divided by the listed population gives a PPP per capita of $9,135. Similarly, the calculated GDP per capita from given figures is $6,757 instead of the listed $5,755.

So, where are the listed numbers comming from?

Also, I'm wondering if we shouldn't be presenting the numbers as a range of estimated values, for example, listing the possible current world populating out to 1 or 2 sigma. (Elustran 00:11, 21 May 2006 (UTC))

[edit] Comparison between economies

This article should obviously include a list of the size of Economies in the world, and comparisons between them. Perhaps a circle graphic would be very explicative. Or perhaps several circle graphics since it is probable that many countries will not be apreciatable in a global one.
