Uruguay's population has slipped past its peak: from a high of 3,398,968 in 2020, it stands at 3,382,537 in 2026. That is a 1.5-fold increase on the 2,234,412 recorded in 1950. Numbers are roughly stable, edging down 0.07% a year. With only 20 people/km², it is one of the world's more sparsely settled countries. Half the population is younger than 36.7 years, and the age structure is steadily tilting older: the median is projected to reach 45.2 by 2050. Women outnumber men, at 94 males per 100 females. By 2100, UN projections see it falling to 2,245,887 (-34% from 2026).
