Talk:List of bordering countries with greatest relative differences in GDP (PPP) per capita

Land borders

Shouldn't this article be renamed "List of bordering countries by land borders with greatest..." or something similar, given that it only includes land borders between countries? For example, it does not include the sea borders between China and Japan, the Philippines and Taiwan, et cetera. -- 李博杰  | —Talk contribs email 19:02, 13 May 2011 (UTC)

Indeed. The 4th place would be Réunion/Madagascar if you include sea borders. An alternative would be to include sea borders in a separate table in this article. Munci (talk) 21:35, 13 May 2011 (UTC)

Valid point. I would however make these observations:

• Good articles need to have their scope managed. For the sake of simplicity we need to set in place some limits as to how much information needs to go in. I am not in favour of expanding the definition of country to include autonomous regions, or internal states etc. I stuck to one simple measure (PPP), when in fact there were a whole raft of measurements to choose. Land borders are a simple enough, but clear concept. WHen this article was being reviewed for DYK? status I took on board several comments, but nobody raised the issue of explictly referring to "land borders"
• Neighbouring countries tend to interact moreso through land than sea borders.
• There are plenty of maritime borders that are in dispute - far more than land borders. China thinks it has a maritime border with Brunei, but most if not all other countries think otherwise. I would not want this article to become a magnet for people to add or caveat entries under dispute. Kransky (talk) 12:15, 15 May 2011 (UTC)

• While a manageable scope is important, this list looses its value when it excludes all island countries, or leaves out common comparisons between two countries which have no land border. Obvious omissions would be Japan, Taiwan, Australia, New Zealand, etc, which leaves much to be desired, since comparisons between Taiwan/China and Japan/China are fairly commonplace.--Huaiwei (talk) 16:43, 21 May 2011 (UTC)

• New Zealand is too far away from Australia to say there's a maritime border. 116.48.86.50 (talk) 21:24, 28 December 2012 (UTC)

Ratio column

A ratio is the relation of two numbers, not a single figure. Regardless of that, there is no mathematical validity in assigning a four significant figure ratio to figures that are themselves very much approximations. Kevin McE (talk) 21:55, 13 May 2011 (UTC)

France and Brazil, France and Suriname

Missing.Assif

Macao and China, Hong Kong and China

Both Macao and Hong Kong are autonomous territories, but no countries and should better be omitted from this list. Assif

Australia and Papua New Guinea

There's no land border between them. The same is true between Bahrain and Saudi, or Singapore and Malaysia/Indonesia. 116.48.86.50 (talk) 21:21, 28 December 2012 (UTC)

Australia and Papua New Guinea

What about France and Suriname and France and Brazil? They should be on the list. (Stpaul (talk) 11:13, 22 June 2016 (UTC))
