First World

First World refers to countries that are high on the HDI (Human Development Index), have decent to exemplary healthcare and are the most technologically-advanced. First World formerly referred to countries that were part of NATO, plus countries such as South Korea, Japan, Australia, New Zealand and South Africa. Geographically, "First World Countries" are located in North America, Europe (Southern, Northern and Western), Scandinavia, part of East Asia and part of Oceania. Economically, most of the "First World Countries" are Capitalist, Socially-Libertarian, Socially-Democratic or Socialist (Reference shown in the "External Links" section).

Unfortunately, many "First World Countries" have problems with obesity, mostly caused by the exporting of fast food companies stemming from the United States. This has also caused some countries of the Third World such as Mexico, United Arab Emirates and Nauru to have high rates of obesity.
