Among the countless scholarly handbooks published in recent years this is the first on the demography of Asia. The chapters in this handbook focus on the four-and-a-half-billion people who live in Asia today and their ancestors – especially the extraordinary demographic transition they have experienced since the middle of the last century, the variations in the underlying demographic trends that contribute to their national and subregional differences, and their demographic history. The chapters also include analyses of the causes and consequences of these trends, and population projections describing what the demographic future of Asia might look like. The aim of the handbook is to provide an authoritative and comprehensive reference for researchers, policymakers, students and general readers who are interested in population change in Asia and the world. The purpose of this introductory chapter is to introduce the subject matter and the book. We do not attempt to summarize individual chapters but try to show where they fit into the broader picture as we see it.
Historical population change in Asia and the world
First, what do we mean by ‘Asia’? By convention Asia is often defined geographically as a ‘major region’ or ‘continent’ which comprises that part of the Eurasian landmass (and adjacent islands) located to the east of an imaginary line drawn through the Black Sea, the Caucasus, the Caspian Sea and north along the Ural Mountains to the Arctic Ocean. This historical construction, dating from the eighteenth century (with precursors going back to the ancient Greeks), is Eurocentric in the residual way it classifies ‘Asia’ as everything that is not part of Europe.
The United Nations Statistical Division (UNSD) and the United Nations Population Division (UNPD), use a different classification of ‘major areas and regions of the world’. Table 1.1 lists the countries and territories of Asia according to this geoscheme and groups them in five regions: Eastern, Southern, Central, South-Eastern and Western Asia, respectively (UNSD 1999). The vast stretch of Russia east of the Urals (otherwise known as ‘Northern Asia’) is not included as part of Asia in this scheme. In general the present volume follows this UN classification, although different ways of grouping countries and territories are occasionally used due to constraints imposed by data sources, since different sources, including autonomous agencies within the UN system, define Asia differently. Using this UN definition, Asia is still the largest ‘major area’ of the world in terms of total land area and population size: its surface land area (32 million sq. km) is slightly larger than the second largest (Africa, with 30 million sq. km), and its population (4.4 billion in 2015) is much larger than the second largest (again Africa, with 1.2 billion). Asia accounts for about 23 per cent of the world’s total land area. It is estimated that this area accounted for 60 per cent of the world’s population in 2015 (UNPD 2015), and about 35 per cent of global GDP (estimated using exchange rates) or 41 per cent (using purchasing power parities) (World Bank 2017).
Asia’s share of world population and the global economy have varied considerably through the centuries. According to the detailed historical estimates made by Angus Maddison (2003), in the year AD 1 Asia accounted for 75 per cent of world population and 76 per cent of the global economy, compared to Western Europe’s shares of 11 and 11 per cent, respectively (Western Europe here includes Western, Northern and Southern Europe according to Maddison’s classification). In AD 1000 the proportions had changed only modestly: Asia’s share of world population was 68 per cent and of the global economy 70 per cent; the corresponding proportions for Western Europe were 10 and 9 per cent, respectively. The end of the first millennium was a low point for Europe, and evidence suggests a decline in average living standards in the West. By 1820, however, the picture looks significantly different: Asia still accounts for 68 per cent of world population but only 59 per cent of the global economy, while Western Europe (and its ‘Western Offshoots’ in North America and Oceania) now account for 14 per cent of world population and 25 per cent of the global economy. The West had pulled ahead, and average living standards in the West were now appreciably higher than in Asia.
