Republic of Korea Population Pyramid 2073
Republic of Korea in 2073
United Nations projections (medium variant) put the population of the Republic of Korea at 32,943,025 in 2073. Compared with 2063, when the projection stands at 38,183,167, that represents a decline of 13.7% over ten years.
The median age is projected at 62.9 years, with 16.5 children under 15 and 103.4 people aged 65 or over for every 100 people of working age (15–64). This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
