The report issued Wednesday says that by 2040 the aging populations could shrink the working-age population by more than 15 percent in South Korea and more than 10 percent in China, Japan and Thailand. In China, that would mean a net loss of 90 million workers.
The report covered aged richer countries like Japan and South Korea, rapidly aging middle-income countries such as China, Thailand and Vietnam, and younger, poorer ones like Cambodia and Lao which will start to age rapidly in 20 or 30 years.
