Qatar

With a population of 2,972,215 as of 2025, Qatar ranks 137th globally and is among the world's smallest nations by area at 11,490 km². The country experiences rapid population growth of 3.9% annually, driven partly by immigration, and maintains a notably high population density of 231 people per km² concentrated almost entirely in urban areas—99% of residents live in cities. The median age of 33.5 years reflects a relatively balanced demographic structure, while life expectancy of 82.5 years places the nation among countries with the longest lifespans.

Located in Asia and bordered only by Saudi Arabia, Qatar operates as a constitutional monarchy with Doha as its capital. The official language is Arabic and the currency is the Qatari riyal. Economically, the country has achieved substantial prosperity, with a GDP per capita of $72,525. The fertility rate stands at 1.7 births per woman, indicating below-replacement-level natural increase typical of high-income nations.
