Republic of Korea Population Pyramid 2030
Republic of Korea in 2030
In 2030, the Republic of Korea is projected to have a population of 51,188,583 people. Ten years before, in 2020, the projected population is still 51,858,482 — a ten-year decline of 1.3%.
With a projected median age of 49.4 years, the Republic of Korea would have a youth dependency ratio of 12.7 and an old-age dependency ratio of 37.7 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
