Korea's total population was tallied at 51.36 million in 2017, and it is expected to decline after reaching a peak of 51.94 million in 2028.
Due to the relatively fast aging population, the number of people aged 65 or older in Korea is expected to increase from 7.07 million in 2017 to 18.27 million in 2067.
Due to a decrease in the school-age population, the number of students at each level of elementary school, middle school, high school, and university is expected to decrease by less than half over the next 50 years.
The increase in the total number of households appears coupled with the decrease in the average number of household members, especially the increase in single-person households.？
