Puerto Rico's population is projected to have slipped past its peak: from a high of 3,813,013 in 2001, it is projected at 3,222,688 in 2026. That is up 45% from 2,229,089 in 1950. Numbers are roughly stable, edging down 0.47% a year. Settlement is dense, at 371 people/km². Half the population is younger than 46.2 years, and the age structure is steadily tilting older: the median is projected to reach 54.7 by 2050. Women outnumber men, at 89 males per 100 females. By 2100, UN projections see it falling to 995,625 (-69% from 2026).

Puerto Rico passed its population peak 25 years ago in 2001, and has since declined by 15.5%. The sex ratio of 89 males per 100 females is notably lower than the global average of ~101. The population is aging rapidly; median age will rise from 46 in 2026 to 55 by 2050. Population density is high at 371 people per km². Looking ahead, UN projections show the population falling to 995,625 by 2100, less than a third of 2026's level.
