Mauritius' population is projected to have slipped past its peak: from a high of 1,292,275 in 2015, it is projected at 1,265,059 in 2026. That is a 2.4-fold increase on the 525,558 recorded in 1950. Numbers are roughly stable, edging down 0.27% a year. People are packed in tightly, at 623 people/km², among the most crowded places on Earth. Half the population is younger than 38.3 years, and the age structure is steadily tilting older: the median is projected to reach 49.1 by 2050. The sexes are close to evenly balanced, at 99 males per 100 females. By 2100, UN projections see it falling to 581,716 (-54% from 2026).
