Republic of Korea Population Pyramid 2049
Republic of Korea in 2049
In 2049, the Republic of Korea is projected to have a population of 45,597,294 people. Compared with 2039, when the projection stands at 49,251,889, that represents a decline of 7.4% over ten years.
Half of the population would be younger than 57.4 years, with 7.8% children under 15 and 39.3% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
