Slovenia's population is projected to have slipped past its peak: from a high of 2,118,697 in 2024, it is projected at 2,114,573 in 2026. That is up 46% from 1,446,358 in 1950. Numbers are roughly stable, edging down 0.13% a year. Settlement is fairly dense, at 105 people/km². Half the population is younger than 45.0 years, and the age structure is steadily tilting older: the median is projected to reach 47.9 by 2050. The sexes are close to evenly balanced, at 101 males per 100 females. By 2100, UN projections see it falling to 1,632,031 (-23% from 2026).
