Hong Kong's population is projected to have slipped past its peak: from a high of 7,490,235 in 2020, it is projected at 7,378,602 in 2026. That is a 4-fold increase on the 1,978,342 recorded in 1950. Numbers are roughly stable, edging down 0.46% a year. People are packed in tightly, at 6,714 people/km², among the most crowded places on Earth. Half the population is younger than 47.9 years, and the age structure is steadily tilting older: the median is projected to reach 62.0 by 2050. Women outnumber men, at 82 males per 100 females. By 2100, UN projections see it falling to 2,080,291 (-72% from 2026).

Hong Kong passed its population peak 6 years ago in 2020, and has since declined by 1.5%. The sex ratio of 82 males per 100 females is notably lower than the global average of ~101. The population is aging rapidly; median age will rise from 48 in 2026 to 62 by 2050. Population density is high at 6,714 people per km². Looking ahead, UN projections show the population falling to 2.1M by 2100, less than half of 2026's level.
