There may be even more scope for seasonal work in East and Southeast Asia in the future. The next 30 years will see a large decline in the working-age population in these regions, which can be expected to impact seasonal labor-intensive activities. The working-age population (15–64 years) for Asian Development Bank member economies in East and Southeast Asia is forecast to decline by 150 million between 2015 and 2050 (Table 4).¹⁸ The largest source of decline will be in the People's Republic of China, where the working-age population will fall by 200 million from 2015 to 2050. There will also be large declines in Japan; Thailand; the Republic of Korea; and Taipei,China. While Indonesia and the Philippines are forecast to each add about 40 million and 36 million people, respectively to their working-age population during the review period—and Myanmar, Malaysia, Viet Nam, and Cambodia between 4 and 8 million each—the net effect will still be a decline that is equivalent to almost 10% of the 2015 working-age population in East and Southeast Asia. Most countries in the Pacific are too small and slow-growing to help supply this future labor deficit, but scope exists from the rapidly growing populations of the Melanesian countries and Timor-Leste. Between 2015 and 2050, these five countries are forecast to add 5.7 million people of working age: 4.4 million in Papua New Guinea, 0.8 million in Timor-Leste, 0.4 million in Solomon Islands, 0.1 million in Vanuatu, and no increase in Fiji.¹⁹
