Talk:Dependency ratio

From Wikipedia, the free encyclopedia

Why does this formula suggest to multiply the number for the age group between 15 and 64 by 100? "Advanced Geography" (by Garret Nagle, published by Oxford University Press) simply divides the number of the "not-productive" by the number of "productive". And this appears to be right of you try to apply both formulas suggested here (either with or without the multiplication by 100) to the figures given at http://devdata.worldbank.org/genderstats/genderRpt.asp?rpt=basic&cty=IND,India&hm=home2 you'll find that the formula with the multiplier provides a wrong value for the dependency ratio.

[edit] Fair use rationale for Image:Pyat rublei 1997.jpg

Image:Pyat rublei 1997.jpg is being used on this article. I notice the image page specifies that the image is being used under fair use but there is no explanation or rationale as to why its use in this Wikipedia article constitutes fair use. In addition to the boilerplate fair use template, you must also write out on the image description page a specific explanation or rationale for why using this image in each article is consistent with fair use.

Please go to the image description page and edit it to include a fair use rationale. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to insure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If there is other fair use media, consider checking that you have specified the fair use rationale on the other images used on this page. Note that any fair use images uploaded after 4 May, 2006, and lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you.

[edit] 15 too young

Most 15-year-olds, and many first-year postsecondary students, are dependent on their parents. Wouldn't 20 be a better cut-off point, at least in industrialized countries? NeonMerlin 21:14, 14 February 2008 (UTC)
