In 2026, Macao's population is projected at 723,188. That is a 4-fold increase on the 196,654 recorded in 1950. It is growing modestly, at +0.23% a year, adding about 1.7K people a year. People are packed in tightly, at 22,600 people/km², among the most crowded places on Earth. Half the population is younger than 40.3 years, and the age structure is steadily tilting older: the median is projected to reach 56.2 by 2050. Women outnumber men, at 85 males per 100 females. By 2100, UN projections see it falling to 331,168 (-54% from 2026).
