Montevideo is the capital and largest city of Uruguay. Based on the most recent official census data, the city proper has a population of about 1.3 million people, while the metropolitan area (urban agglomeration) is roughly around 1.7 to 1.8 million, depending on the exact geographic boundaries used for the broader urban area. The latest widely cited figures place the city proper at approximately 1.30 million inhabitants and the metro/urban figure approaching 1.8 million, which represents about half to a bit more of Uruguay’s total population. Key points:

• City proper population: ~1.30 million.
• Urban/metropolitan population: ~1.75–1.80 million.
• Share of national population: Montevideo accounts for a substantial portion of Uruguay’s residents, roughly one-third to nearly half, depending on whether you count the city proper or the broader metro area.
