Country Overview

South Korea, formally the Republic of Korea, occupies the southern part of the Korean Peninsula and is a major advanced industrial and technological economy. Seoul is the national capital and the center of a metropolitan region housing more than half of the population. The country is a constitutional presidential republic led by President Lee Jae-myung, elected in June 2025 after the removal of his predecessor; Han Seong-sook took office as prime minister in July 2026. Its economy is especially prominent in semiconductors, automobiles, shipbuilding and digital services. This reference profile explicitly separates the national 2025 census from World Bank population estimates, identifies merchandise trade by reporting year, and presents the North–South Korea division and heritage inscriptions with precise qualifications.

The World Bank lists 2025 GDP of US$1,872.37 billion and 1.0% real growth. South Korea’s Ministry of Trade reported US$709.7 billion exports and US$631.7 billion imports for calendar 2025. Prime Minister Han Seong-sook began serving July 1, 2026, superseding earlier references to Kim Min-seok. UNESCO currently lists 17 inscribed properties; the 2026 Getbol extension did not create a separately numbered eighteenth property.

Sources and Methodology

The Ministry of Data and Statistics 2025 register-based census counted 51.82 million persons (November 1, 2025), whereas the World Bank 2025 annual estimated total is 51,684,564. GDP uses the World Bank’s nominal current-US$ series, with annual real growth distinguished from nominal output. The Korean Ministry of Trade’s 2025 exports (US$709.7bn) and imports (US$631.7bn) are not the WTO 2024 international goods profile. The 2026 premier is Han Seong-sook, who took office July 1, not Kim Min-seok. UNESCO reports 17 inscribed properties; the 2026 Getbol territorial extension did not add a separate property. Political and international descriptions have a November 6, 2026 editorial cutoff.
