Japan's population is projected to have slipped past its peak: from a high of 128,192,470 in 2009, it is projected at 122,427,731 in 2026. That is up 42% from 86,443,277 in 1950. The population is shrinking by 0.56% a year, losing about 688K people a year. Settlement is fairly dense, at 325 people/km². Half the population is younger than 50.2 years, and the age structure is steadily tilting older: the median is projected to reach 52.8 by 2050. Women outnumber men, at 95 males per 100 females. By 2100, UN projections see it falling to 76,845,989 (-37% from 2026).
