Reference excerpt

This is a list of countries and territories by the United Nations geoscheme, including 193 UN member states, two UN observer states (the Holy See and Palestine), two states in free association with New Zealand (the Cook Islands and Niue), and 49 non-sovereign dependencies or territories, as well as Western Sahara (a disputed territory whose sovereignty is contested) and Antarctica. In total, 248 countries and territories have been listed. Not included in the list are eight de facto states (whose sovereignty are not recognised by the United Nations), the Sovereign Base Areas of Akrotiri and Dhekelia (SBA), and four uninhabited territories (the Ashmore and Cartier Islands, Clipperton Island, the Coral Sea Islands, and Navassa Island). Kosovo and Taiwan (listed as Taiwan Province of China) have been separately listed for strictly statistical purposes.

Lists The United Nations geoscheme was created for statistical analysis and consists of six continental regions, 22 geographical subregions, and two intermediary regions. The United Nations Statistics Division created and maintains the M49 – Standard country or area codes for statistical use. The codes are listed from smallest to largest region, left to right.

Worked examples

Example 1 — a first encounter with List of countries and territories by the United Nations geoscheme

Start with the simplest possible case. Write down what List of countries and territories by the United Nations geoscheme claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of countries and territories by the United Nations geoscheme before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of countries and territories by the United Nations geoscheme ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of countries and territories by the United Nations geoscheme

In research: List of countries and territories by the United Nations geoscheme appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of countries and territories by the United Nations geoscheme in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
