Country Overview
Yemen occupies the southwestern corner of the Arabian Peninsula, overlooking the Red Sea, Gulf of Aden and Bab al-Mandab maritime passage. It was formed through the 1990 union of North and South Yemen, but a prolonged conflict has divided its political and economic institutions. Sana’a remains the constitutional capital and is controlled by the Houthi movement; the internationally recognized Presidential Leadership Council and government have operated from Aden and other locations. Humanitarian, GDP and displacement statistics require particularly careful source and date labeling.

Data and status note: Yemen’s population is an international statistical estimate rather than a current full national census: the World Bank reports 41,773,878 residents for 2025. The UN’s 2026 humanitarian plan assesses 22.3 million people in need, including 5.2 million internally displaced. The World Bank estimates a real GDP contraction of 1.5 percent in 2025; its public nominal-dollar GDP series has not been updated past 2018. UNESCO lists five World Heritage properties, four of them on its List of World Heritage in Danger.

Sources & Methodology
Current population is a modeled estimate; there has been no comprehensive conflict-era census covering Yemen with reliable nationwide enumeration. Constitutional sovereignty, internationally recognized executive leadership and actual territorial control are distinct. The national economy has fragmented into separate financial and monetary zones. The World Bank’s real-GDP growth estimate for 2025 must not be confused with a currently reported nominal-dollar GDP level; its displayed nominal series ends in 2018. The UN’s March 2026 humanitarian planning total differs from some earlier planning documents. UNESCO has five inscriptions, of which four are separately listed as endangered.
Editorial cutoff: November 6, 2026 (Pacific Time). This is a dated reference edition; official statistical and political updates after the cutoff require review.
