Ireland

Ireland is a sovereign state in Northern Europe, classified by the United Nations as a member state in the UN M49 system. Its ISO alpha-2 code is IE and its ISO alpha-3 code is IRL. The UN lists Ireland under the region Europe and the subregion Northern Europe. The World Bank records Dublin as the seat of government in its country metadata. These identifiers are statistical and administrative facts, not political or territorial assertions.

Country identifiers

Ireland is a member of the United Nations. Its UN M49 code is part of the standard statistical framework used by the UN for international data comparison. The ISO codes (IE, IRL) are maintained by the International Organization for Standardization and are used across internet domains, banking, and international shipping.

Stable identifiers you can verify directly:

• UN M49 code: 372
• ISO alpha-2: IE
• ISO alpha-3: IRL
• UN region: Europe
• UN subregion: Northern Europe
• UN membership: Member state
• World Bank seat-of-government field: Dublin

These codes are maintained by the UN Statistics Division and the ISO. They are administrative labels, not statements about sovereignty or territorial extent. For the authoritative overview of M49 coding, see the UN Statistics Division methodology page.

Geography and official languages

The World Bank lists Dublin as the seat of government in its country API. That API also provides the official country code (IE), region (Europe), and income grouping, but the exact population figure changes every year and is not a stable property of any reference page.

For the current population, use the UN World Population Prospects (published every two years) or the Central Statistics Office Ireland, the national statistical office. Census data is the most reliable count but is conducted only every five years and will lag behind the latest estimate. When you compare population figures, note the reference year and whether the number is a census count, an estimate, or a projection. For a quick cross-check, the World Bank country API returns the latest official population estimate with its own source year, but it will not match the UN figure exactly because the definitions and revision dates differ.

Seat of government: Dublin. The World Bank field lists Dublin; this is an administrative fact, not a political claim.

Currency: the euro (EUR). Ireland is part of the euro area, so the currency is managed by the European Central Bank, not by the national government alone.

Language: Irish (Gaeilge) is the national and first official language; English is the second official language and is the most widely spoken in daily life. The Constitution of Ireland names Irish as the first official language, while legislation and official documents are also issued in English.

How to verify current facts without freezing volatile figures

Population, currency, government, and visa rules change faster than any static reference can capture. For every figure below, check the named source and reference year before citing it.

Population sources and reference years

The UN World Population Prospects releases revised estimates every two years. The latest revision may differ from older census counts; national statistical offices (CSO Ireland) run the census, while the UN harmonises definitions across jurisdictions. The most recent census was held in 2022; the CSO’s current figure should always be cited with its release date. The World Bank indicator SP.POP.TOTL is typically based on UN World Population Prospects data. Always note the reference year because figures change annually and the underlying census may be several years old.

Language-use data

Irish (Gaeilge) and English are the official languages; the Constitution names Irish as the first official language and English as a second official language. Language-use statistics come from census data, usually every five years (CSO Ireland).

Currency and monetary authority

The euro (EUR, ISO 4217 code) is the currency of the Republic of Ireland. The Central Bank of Ireland publishes current legal tender information. For the whole island, note that Northern Ireland is part of the United Kingdom and uses the pound sterling (GBP). Currency values change daily.

Government structure and current officeholders

Ireland is a parliamentary democracy. The head of government is the Taoiseach (prime minister). The head of state is the President. These roles and the current officeholders should be verified from official Irish government sources at the time of reading.

Economic indicators and definitions

GDP and related indicators are published by the World Bank, IMF, and Ireland’s Central Statistics Office (CSO). Definitions differ (nominal vs PPP, per capita vs total) and are not interchangeable.

Travel and entry requirements

Entry rules, visa requirements, and safety guidance change frequently; check your own government’s travel advisory and the Irish immigration authority for current rules.
