ISO 3166-1 in the context of "List of countries and outlying territories by total area"

This is a list of countries and dependencies by population. It includes sovereign states, inhabited dependent territories and, in some cases, constituent countries of sovereign states, with inclusion within the list being primarily based on the ISO standard ISO 3166-1. For instance, the United Kingdom is considered a single entity, while the constituent countries of the Kingdom of the Netherlands are considered separately. In addition, this list includes certain states with limited recognition not found in ISO 3166-1. Also given in a percentage is each country's population compared with the world population, which the United Nations estimated at 8.232 billion as of 2025.

The following is a list of countries and dependencies ranked by population density, sorted by inhabitants per square kilometre or square mile. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1. The list also includes unrecognized but de facto independent countries. The figures in the table are based on areas including internal bodies of water such as bays, lakes, reservoirs and rivers. The list does not include entities not on ISO 3166-1, except for states with limited recognition. Thus constituent countries that are not included on ISO 3166-1, and other entities not on ISO 3166-1 such as the European Union, are not included.

Unless otherwise noted, areas and populations are sourced from the United Nations World Population Prospects, which uses the latest censuses and official figures, as well as figures from the Food and Agriculture Organization, an agency of the UN. Data is current as of 2025.

The United States Minor Outlying Islands is a statistical designation applying to the minor outlying islands and groups of islands that comprise eight United States insular areas and territories in the Pacific Ocean (Baker Island, Howland Island, Jarvis Island, Johnston Atoll, Kingman Reef, Midway Atoll, Palmyra Atoll, and Wake Island) and one in the Caribbean Sea (Navassa Island).

It is defined by the International Organization for Standardization's ISO 3166-1 code. The entry code is ISO 3166-2:UM.

This is a list of countries by trade-to-GDP ratio, i.e. the sum of exports and imports of goods and services, divided by gross domestic product, expressed as a percentage, based on the data published by World Bank. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.

Imports of goods and services represent the value of all goods and other market services received from the rest of the world. Exports of goods and services represent the value of all goods and other market services provided to the rest of the world. They include the value of merchandise, freight, insurance, transport, travel, royalties, license fees, and other services, such as communication, construction, financial, information, business, personal, and government services. They exclude compensation of employees and investment income (formerly called factor services) and transfer payments. The trade-to-GDP ratio is also known as the "trade openness index".

UN M49 or the Standard Country or Area Codes for Statistical Use (Series M, No. 49) is a standard for area codes used by the United Nations for statistical purposes, developed and maintained by the United Nations Statistics Division. Each area code is a 3-digit number which can refer to a wide variety of geographical and political regions, like a continent and a country. Codes assigned in the system generally do not change when the country or area's name changes (unlike ISO 3166-1 alpha-2 or ISO 3166-1 alpha-3), but instead change when the territorial extent of the country or area changes significantly, although there have been exceptions to this rule.

Some of these codes, those representing countries and territories, were first included as part of the ISO 3166-1 standard in its second edition in 1981, but they have been released by the United Nations Statistics Division since 1970.

This is a list of countries by net goods exports, also known as balance of trade, which is the difference between the monetary value of a nation's exports and imports over a certain time period.The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.

The following table shows the value of total annual merchandise exports and imports, expressed in millions of United States dollars (current prices), and the resulting trade balance, according to United Nations Conference on Trade and Development (UNCTAD), World Trade Organization (WTO), and World Bank (WB). Countries with positive balance of trade have a trade surplus, countries with negative net exports have a trade deficit.

ISO 3166-1 alpha-2 codes are two-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They are the most widely used of the country codes published by ISO (the others being alpha-3 and numeric), and are used most prominently for the Internet's country code top-level domains (with a few exceptions). They were first included as part of the ISO 3166 standard in its first edition in 1974.

ISO 3166-2 is part of the ISO 3166 standard published by the International Organization for Standardization (ISO), and defines codes for identifying the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. The official name of the standard is Codes for the representation of names of countries and their subdivisions – Part 2: Country subdivision code. It was first published in 1998.

The purpose of ISO 3166-2 is to establish an international standard of short and unique alphanumeric codes to represent the relevant administrative divisions and dependent territories of all countries in a more convenient and less ambiguous form than their full names. Each complete ISO 3166-2 code consists of two parts, separated by a hyphen:

ISO 3166-1 alpha-3 codes are three-letter country codes defined in ISO 3166-1, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), to represent countries, dependent territories, and special areas of geographical interest. They allow a better visual association between the codes and the country names than the two-letter alpha-2 codes (the third set of codes is numeric and hence offers no visual association). They were first included as part of the ISO 3166 standard in its first edition in 1974.

This is the list of countries by flows of foreign direct investment (FDI) abroad. The list includes sovereign states and self-governing dependent territories based upon the ISO standard ISO 3166-1.

According to the World Bank, "Foreign Direct Investment (FDI) refers to direct investment equity flows in an economy. It is the sum of equity capital, reinvestment of earnings, and other capital. Direct investment is a category of cross-border investment associated with a resident in one economy having control or a significant degree of influence on the management of an enterprise that is resident in another economy. Ownership of 10 percent or more of the ordinary shares of voting stock is the criterion for determining the existence of a direct investment relationship. In the following table, WB figures shows net outflows of investment from the reporting economy to the rest of the world. Data are in current U.S. dollars."
