分享 All the world's gold
insight 2014-10-9 20:04
http://www.numbersleuth.org/worlds-gold/ Embed this infographic on your site! All The World's Gold We here at NumberSleuth are all about exploring the world of numbers, and with this infographic we decided to take a look at the numbers behind the entire amount of gold in the world as well as other facts about gold. Below are a series of questions that we began with and the answers we discovered in our research. We believe that this is the most thorough and in-depth resource with facts about the world's gold on the Internet and we hope you have as much fun reading through the information as we did in putting it all together. 1. How much above-ground gold (gold that has been mined) is there in all the world? The best estimate at the end of 2011 is that around 165,000 metric tons (or tonnes) have been mined in all of human history. That’s about 181,881 ordinary tons or 363,762,732 pounds, or 5,820,203,717 ordinary ounces. Gold typically is measured in what are known as troy ounces, which are a little bigger than ordinary ounces (a troy ounce is 31.1034768 grams whereas an ordinary ounce is 28.3495231 grams). There are 32.1507466 troy ounces in a kilogram or 32,150.7466 troy ounces in a metric ton. “More than half of all humanity’s gold has been extracted in the past 50 years. Now the world’s richest deposits are fast being depleted, and new discoveries are rare. Gone are the hundred-mile-long gold reefs in South Africa or cherry-size nuggets in California. Most of the gold left to mine exists as traces buried in remote and fragile corners of the globe. It's an invitation to destruction. But there is no shortage of miners, big and small, who are willing to accept.” SOURCES: http://ngm.nationalgeographic.com/print/2009/01/gold/larmer-text , http://www.gold.org/about_gold , and http://minerals.usgs.gov . 2. How much gold gets mined per year worldwide? The table below shows world gold production from 1900 thru 2011. Production in 1900 was around 400 metric tons per year and has consistently moved up over the years. It is currently around 2,500 metric tons per year. The all time high was reached in 2001, with 2,600 metric tons of gold production worldwide. The total gold mined from 1900 to the present is just under 141,000 metric tons. Given that humans have mined a total of 165,000 metric tons over the course of history, that leaves just 24,000 metric tons mined before the 20thcentury.

But didn’t the Spanish get lots and lots of gold from the New World, especially from the Aztecs and Incas? In fact, the Spanish got much more silver than gold from the New World. In the 16thcentury, when production was in full swing, the Spanish only got 154 metric tons of gold, whereas they got 7440 metric tons of silver. Gold production in the new world for the entire the 16thcentury was thus less than half of what it was worldwide in 1900. Here is a comparison, decade by decade, of Spanish gold and silver production in the New World in the 16thcentury: Year value in millions of pesos gold (in metric tons) silver (in metric tons) 1503-1510 1.18 5 0 1511-1520 2.18 9.2 0 1521-1530 1.17 4.9 0 1531-1540 5.58 14.5 86 1541-1550 10.46 25 178 1551-1560 17.86 42.6 303 1561-1570 25.34 11.5 943 1571-1580 29.15 9.4 1119 1581-1590 53.2 12.1 2103 1591-1600 69.6 19.5 2708 SOURCE: http://mygeologypage.ucdavis.edu/cowen/~GEL115/115ch8.html 4. How much gold, really, is 165,000 metric tons (the total mined throughout human history) and 2,500 metric tons (the total that’s currently mined annually)? An Olympic swimming pool is 50 by 25 by 2 meters. It therefore contains 2,500 cubic meters of water. Each cubic meter of water is one metric ton. Gold is 19.3 times as dense as water. Therefore an Olympic swimming pool would contain 48,250 metric tons of gold. It follows that 3.42 Olympic-sized swimming pools could contain all the gold that’s ever been mined. Another way to imagine this is to think of all the gold in the world ever mined as a single cube. That would be a cube with each side just over 20 meters, or 67 feet, in length. Given that about 2,500 metric tons of gold is mined each year, this annual production of gold would fit in a cube whose sides were 5 meters, or 16.6 feet, in length. All the production of gold in the world for a given year would thus fit in a 20 by 30 foot room with an 8 foot ceiling. 5. Given 165,000 metric tons as an upper bound on available gold, how much does that leave to each human on the planet? Humanity has just hit the 7 billion mark. That leaves just under 24 grams of gold to each person on planet earth, or .76 troy ounces or .83 ordinary ounces per person. In an ordinary male gold wedding band at 18-karat purity, there are about 5 grams of pure gold. That means every person on planet earth could own about 5 gold rings. At the current price of $1,750.00 per troy ounce of gold, that leaves $1,326.00 in gold for each person on planet earth. “Gold production has increased by a factor of 2.1 from 1959 to 2010. At the same time, the world population has been multiplied by a factor 2.2. Thus we produced more or less the same amount of gold per inhabitant as in 1959.” http://www.forbes.com/sites/afontevecchia/2010/11/19/how-many-olympic-sized-swimming-pools-can-we-fill-with-billionaire-gold More Gold Facts

分享 区域经济统计yearbook 2007 sichuan数字错误
susilila 2014-4-20 09:09
The fundamental errors occur to Sichuan Province as the yearbook reports the exact same numbers on the urban employed persons and the total investment in fixed assets, which in any means and by any sense should not be be same. This might occur due to complete negligence and reckless absent-mindness among bureaucrats. Moreover, due to the extra duplicate numbers, the other numbers after that column is completely messed up. For instance, the budget revenue is a few times higher than the budget outlays, which theoretically is very nice. However, artificial adjustments for the numbers only create utopian dreams that can not stand a chance to be reality. Thirdly, the average wage among the urban employed are not correct as the numbers may indeed reflect the amount of disposable income among them, which often add other sources of income to their wages. The problem here is that there are limited ways to figure out what those numbers really mean. For the number of average wage among the urban employed, I personally offer a fix by recommending the use of the annual yearbook of sichuan province.

U.S. Treasury now openly 'cooking the books' to fudge debt numbers in desperate move before collapse Friday, August 02, 2013 by: J. D. Heyes Learn more: http://www.naturalnews.com/041457_US_Treasury_national_debt_creative_accounting.html#ixzz2fuBqjzO7 (NaturalNews) On the surface, it appears as though the federal government is finally making progress on the national debt. But in reality, when you apply some common sense and a little logic, it becomes obvious that what is really going on is no small amount of creative math. In case you didn't know it, the "official" national debt has been the same for more than 70 days. How is that possible, considering the national debt climbs about a million dollars a minute ? According to CNSNews.com , which has analyzed the ongoing U.S. Treasury debt data, the federal debt has been stuck at exactly $16,699,396,000,000.00 for more 70 days, as of July 29. That's about $25 million below the congressionally authorized legal limit of $16,699,421,095,673.60: The portion of the federal debt subject to the legal limit set by Congress first hit $16,699,396,000,000.00 at the close of business on May 17. At the close of every business day since then, it has also been $16,699,396,000,000.00, according to the official accounting published by the Treasury Department. We should exceed the debt limit in the next 25 minutes, but... Mind you, if the debt had increased by a penny more at any time during that period, it would have exceeded the statutory limit and would have become a violation of the law. Treasury says that hasn't happened, however - despite the fact that, as of this writing, USDebtClock.org has the nation's debt at well above that statutory limit (in excess of $16.884 trillion). There's more. "Even though the government's official accounting of the debt has not budged for 70 days, the Treasury has continued to sell bills, notes and bonds at a value that exceeds the value of the bills, notes and bonds it was redeeming," CNS News reported. Indeed, according to the Daily Treasury Statement for May 17, the department, by then, had redeemed $4,776,995,000,000.00 since the start of the fiscal year, Oct. 1, 2012. As of that date, Treasury had already sold off $5,354,508,000.000.00 in new bills, bonds and notes so far. "That represented a net increase in publicly circulating U.S. government debt instruments of $577,513,000,000.00 for the fiscal year," CNS News said. In addition: As of July 26, according to the latest Treasury statement, the Treasury had already redeemed approximately $6,128,368,000,000.00 in bills, notes and bonds during this fiscal year. But, at the same time, according to the statement, the Treasury had sold an additional $6,759,148,000,000.00 bills, note and bonds - for a net increase of $630,780,000,000.00 for the year. That means the value of U.S. Treasury debt instruments in public circulation has risen by $53.267 billion since May 17, though Treasury says the debt had not budged a single penny over the same time. How is that possible? How can the value of extant U.S. Treasury securities climb by more than $53 billion over 70 days when the government's debt, which is subject to legal limitations, remained the same? Not a peep from Congress or the White House on Treasury's creative math "On May 17, the day the debt began its long stay at $16,699,396,000,000.00, Treasury Secretary Lew sent a letter to House Speaker John Boehner," CNS News reported. "In the letter, Lew said the Treasury would begin implementing what he called 'the standard set of extraordinary measures' that allows the Treasury to continue to borrow and spend money even after it has hit the legal debt limit." Meanwhile, the real national debt continues to skyrocket - even as lawmakers pretend to be "gearing up" for "another debt ceiling fight" this fall. Incredibly, this report from Business Insider said, "Analysts don't expect that the nation's debt limit will need to be raised before mid-October or mid-November, but House Republicans and the White House are already trading familiar words about the process." Apparently the mainstream media, along with members of Congress and the White House, are fine with permitting this creative use of math at the Treasury Department to artificially hold down the nation's debt until lawmakers are "ready" to discuss it - sometime after the summer recess.
