Country in the context of "Island country"

A capital city, or just capital, is the municipality holding primary status in a country, state, province, department, or other subnational division, usually as its seat of government. A capital is typically a city that physically encompasses the government's offices and meeting places; the status as capital is often designated by law or a constitution. In some jurisdictions, including several countries, different branches of government are in different settlements, sometimes meaning there are multiple official capitals. In some cases, a distinction is made between the official (constitutional) capital and the seat of government.

English-language media often use the name of the capital metonymically to refer to the government sitting there. Thus, "London–Washington relations" is understood to mean diplomatic relations between Great Britain and the United States.

A state is a political entity that regulates society and the population within a definite territory. Government is considered to form the fundamental apparatus of contemporary states.

A country often has a single state, with various administrative divisions. A state may be a unitary state or some type of federal union; in the latter type, the term "state" is sometimes used to refer to the federated polities that make up the federation, and they may have some of the attributes of a sovereign state, except being under their federation and without the same capacity to act internationally. (Other terms that are used in such federal systems may include "province", "region" or other terms.)

A province is an administrative division within a country or state. The term derives from the ancient Roman provincia, which was the major territorial and administrative unit of the Roman Empire's territorial possessions outside Italy. The term province has since been adopted by many countries. In some countries with no actual provinces, "the provinces" is a metaphorical term meaning "outside the capital city".

While some provinces were produced artificially by colonial powers, others were formed around local groups with their own ethnic identities. Many have their own powers independent of central or federal authority, especially in Canada and Pakistan. In other countries, like China or France, provinces are the creation of central government, with very little autonomy.

A city-state is an independent sovereign city which serves as the center of political, economic, and cultural life over its contiguous territory, as opposed to a regular state or country comprising a capital city and other cities and/or a countryside. City-states have existed in many parts of the world throughout history, including cities such as Rome, Carthage, Athens and Sparta and the Italian city-states during the Middle Ages and Renaissance, such as Florence, Venice, Genoa and Milan.

With the rise of nation states worldwide, there remains some disagreement on the number of modern city-states that still exist; Singapore, Monaco and Vatican City are the candidates most commonly discussed. Out of these, Singapore is the largest and most populous city-state in the world, with full sovereignty, international borders, its own currency, a robust military, and substantial international influence in its own right. The Economist refers to it as the "world's only fully functioning city-state".

Mainland is defined as "relating to or forming the main part of a country or continent, not including the islands around it [regardless of status under territorial jurisdiction by an entity]." The term is often politically, economically and/or demographically more significant than politically associated remote territories, such as exclaves or oceanic islands situated outside the continental shelf.

In geography, "mainland" can denote the continental part of any polity or the main island within an island nation. In geopolitics, "mainland" is sometimes used interchangeably with terms like metropole as an antonym to overseas territories. In the sense of "heartland", mainland is the opposite of periphery. In some language a separate concept of "mainland" is missing and is replaced with a "continental portion".

Gross domestic product (GDP) is a monetary measure of the total market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic activity of a country or region. The major components of GDP are consumption, government spending, net exports (exports minus imports), and investment. Changing any of these factors can increase the size of the economy. For example, population growth through mass immigration can raise consumption and demand for public services, thereby contributing to GDP growth. However, GDP is not a measure of overall standard of living or well-being, as it does not account for how income is distributed among the population. A country may rank high in GDP but still experience jobless growth depending on its planned economic structure and strategies. Dividing total GDP by the population gives an idealized rough measure of GDP per capita. Several national and international economic organizations, such as the OECD and the International Monetary Fund, maintain their own definitions of GDP.

GDP is often used as a metric for international comparisons as well as a broad measure of economic progress. It serves as a statistical indicator of national development and progress. Total GDP can also be broken down into the contribution of each industry or sector of the economy. Nominal GDP is useful when comparing national economies on the international market using current exchange rate. To compare economies over time inflation can be adjusted by comparing real instead of nominal values. For cross-country comparisons, GDP figures are often adjusted for differences in the cost of living using purchasing power parity (PPP). GDP per capita at purchasing power parity can be useful for comparing living standards between nations.

A sovereign state is a state that has the highest authority over a territory. It is commonly understood that a sovereign state is independent. When referring to a specific polity, the term "country" may also refer to a constituent country, or a dependent territory.

A sovereign state is required to have a permanent population, defined territory, a government not under another, and the capacity to interact with other sovereign states. In actual practice, recognition or non-recognition by other states plays an important role in determining the status of a country. Unrecognized states often have difficulty engaging in diplomatic relations with other sovereign states.
