Uruguay

Uruguay

Uruguay is a stable country research profile. The classification facts below come from the United Nations Statistics Division (UNSD) and are stable identifiers, not volatile statistics. Uruguay’s UN M49 code is 858, its ISO alpha-2 code is UY, and its ISO alpha-3 code is URY. The UN assigns Uruguay to the region of the Americas and the subregion of Latin America and the Caribbean. Uruguay is a UN member state. The World Bank lists the seat of government as Montevideo. These classification facts are structural, not political claims; they follow the UN M49 standard used for statistical comparability. For the authoritative overview of these codes and regional groupings, see the UN M49 overview.

How to verify the core facts

The UN M49 standard assigns Uruguay the numeric code 858 and the ISO codes UY and URY. These codes are stable identifiers used across international databases. Montevideo is recognised in the World Bank country API and in UN M49 documentation. Do not treat these codes as political statements; they are statistical identifiers.

For current population, the most reliable primary source is Uruguay’s national statistical office, the Instituto Nacional de Estadística (INE). The UN Population Division publishes annual estimates and projections; the World Bank’s country API returns figures with a reference year. Each dataset defines population differently, de facto vs de jure, census vs projection, so always name the source and year when citing a number. As of the 2023 census cycle, Uruguay’s inhabitants were counted at approximately 3.4 million people; the UN’s 2024 revision estimated around 3.39 million (UN DESA, 2024).

Population

Population figures change continuously, so any single number is a snapshot, not a fixed fact. The UN Population Division publishes annual estimates and projections; the World Bank and national statistics office use census and survey data. For Uruguay, the most recent UN estimate is around 3.4 million people (UN DESA, World Population Prospects, 2024 revision). The national source is the Instituto Nacional de Estadística (INE Uruguay). Census data is collected roughly every 10 years; the last full census was in 2011, so current figures are projections, not counts.

Which source to use for which purpose

Choose your source based on what you need to measure. The UN World Population Prospects give internationally comparable estimates and projections, updated every two years. The World Bank API returns a single figure per year with clear metadata, useful for cross-country charts. INE Uruguay provides the most granular domestic data, including departmental breakdowns and intercensal projections. None of these sources is inherently better; they serve different analytical needs.

Census vs estimate: a practical distinction

A census attempts a complete count and typically happens once a decade. An estimate uses birth, death and migration data to project forward from the last census. Uruguay’s 2011 census is the most recent full count; the 2023 census cycle produced updated figures that are now the baseline for current projections. When you cite a number, specify whether it comes from a census or an estimate and name the reference year.

Capital, languages, and currency

Montevideo is the seat of government and largest city. The language of administration is Spanish; Uruguayan Spanish has distinctive features but is mutually intelligible with other varieties. The currency is the Uruguayan peso (UYU), issued by the Central Bank of Uruguay. Exchange rates change daily; check a current financial data source for today’s rate. No single number on this page is a live quote.

What the language law actually says

The 2008 Ley de Educación (Law No. 18.437) establishes Spanish as the language of instruction and administration. Uruguayan Spanish has distinctive features, including voseo and Italian-influenced vocabulary. Portuñol, a Portuguese-Spanish mix, is spoken near the Brazilian border. There is no standalone language law declaring Spanish the sole language of the republic; the education law is the primary legal reference.

Currency identifiers and where to check them

The ISO 4217 code for the Uruguayan peso is UYU. The Central Bank of Uruguay (Banco Central del Uruguay) issues banknotes and coins and publishes the reference exchange rate. For live rates, consult a financial data provider; this page does not display real-time quotes.

People, language and culture

Figures for the number of inhabitants change every year, so do not rely on a static number. The United Nations Population Division publishes annual estimates; the World Bank API returns the latest total with its own metadata. National censuses are conducted roughly every ten years by the Instituto Nacional de Estadística (INE Uruguay); the most recent census was in 2023. For historical and projected figures, the UN World Population Prospects is the standard source.

UNESCO provides education and cultural statistics, while the World Bank publishes learning-adjusted years of schooling. Literacy and enrolment figures from the UNESCO Institute for Statistics use definitions that differ across countries; always cite the year and source when comparing.

Government and economy

Montevideo is listed in the World Bank capital field. For current executive, legislative and electoral data, use the government portal (presidencia.gub.uy) and the Uruguayan Parliament’s site. For economic indicators, use World Bank country indicators and IMF Article IV reports; name the reference year. For currency, check the Central Bank of Uruguay for the current code and issued banknotes.

How to pull economic indicators without mixing datasets

Use the World Bank country API to pull the latest GDP per capita, GNI per capita, and income classification. The API returns metadata with the reference year in the “date” field. IMF and OECD also publish cross-country outlooks, but their definitions and vintages differ from the World Bank; do not mix datasets in a single comparison. HDI (UNDP) and Gini (World Bank) are separate indices; cite each with its own source and year.

Government structure: where to find current information

For the current executive branch, use the Presidencia de la República Oriental del Uruguay portal and note the date of access. Legislative data, including current members and bills, is available through the Parliament’s site. Electoral results and procedures are published by the Corte Electoral. These sources update frequently; a citation without an access date is unreliable.

Population and society: source checklist

• The national statistical office (INE Uruguay) publishes census and projection data; the UN World Population Prospects gives comparable global estimates. Always cite the reference year and the dataset (census vs estimate).
• Languages: Spanish is the language of administration. The 2008 National Institute of Statistics survey is often cited for Uruguayan Spanish and the presence of Portuguese in border regions, but check the current year for updated language data.
• Literacy and education: UNESCO Institute for Statistics provides comparable literacy and enrolment figures; definitions differ, so cite the year and source.
