Gross domestic product per person (GDP per capita) varies considerably across the Asia/Pacific region (). Differences in GDP per capita within the Asia/Pacific region are large: Macau, China’s GDP per capita is more than 100 times higher than in Nepal and Tajikistan. GDP per capita is well above the OECD average (USD 38 200) in the richest economies in the region: Australia, Hong Kong, China, Macau, China, New Zealand and Singapore. By contrast, more than two-thirds of the Asia/Pacific economies have a GDP per capita that is below the regional average (USD 13 800).

The total fertility rate (TFR) gives an indication of the number of children an average woman will have in her lifetime. The size of the population remains stable if the total fertility rate is a little over two, allowing for some mortality during infancy and childhood. This so‐called “replacement rate” is around 2.1 children per women for industrialised countries but it may be higher for poorer countries.

Both marriage and divorce rates have increased in the Asia/Pacific region since 2000 ( and ). Crude marriage rates of Asia/Pacific countries are almost twice as high as the average across OECD countries whilst crude divorce rates are half of the OECD average. Crude marriage rates are highest at over nine marriages per 1 000 adults in China, Kazakhstan and Tajikistan; they are around four marriages per 1 000 adults in Australia, New Zealand and Thailand. Since 2000, crude divorce rates have increased in most Asia/Pacific countries, but not among the OECD countries in the Asia/Pacific region (Australia, Japan, Korea and New Zealand). Overall, countries with higher crude marriage rates tend to have higher crude divorce rates.

The total refugee stock including asylum seekers to the Asia/Pacific area has decreased from 3.9 million in 1990 to 2.6 million in 2017 – data do not account for the recent Rohingya crisis with refugee flows from Myanmar to Bangladesh and India. Over the same period the number of refugees in OECD countries has more than tripled to 7.3 million (). The decline of the number of refugees in Pakistan (1.9 million) contributed to the overall decline in the refugee stock in the Asia/Pacific region. By contrast, the number of refugees increased by more than 100 000 in India and more than 10 000 in China, Indonesia, Japan, Nepal and Thailand.

In 2015, countries in the Asia/Pacific region on average had eleven people of working age for every person over 65 (.A). This is more than twice as high as the OECD’s average. Tajikistan, Maldives, Brunei Darussalam and Mongolia top the list with at least 17 working-age persons per one person of pension age: a stark contrast to Japan’s 2:3 ratio. Within the Asia/Pacific region, OECD countries such as Korea, Japan, Australia and New Zealand have the smallest old-age support ratios compared with non-OECD countries. In these countries life expectancy is high (), while fertility rates are low, particularly in Japan and Korea ().
