Even though South Korea would be integrating nearly 23 million North Koreans who would need large amounts of medical and economic assistance, it would be inheriting a relatively young population, something that would aid in offsetting the South aging population, as well having one of the lowest reproductive rates in the world. The North Korean population is also relatively well-educated for a country of its current condition, and many of its citizens could contribute relatively quickly within an integrated economy. In terms of size, the territory of a unified Korea would nearly double, and within this land lays a windfall of mineral wealth that could indeed vault Korea past Japan and Germany within 40 years.
