PART IāSPECIAL CHAPTER
Poverty in Asia: A Deeper Look
Section 1: Introduction
Asia and the Pacific1 continues to lead the world in reducing extreme poverty.2 The early attainment of the global Millennium Development Goal (MDG) target of cutting extreme poverty in half could not have happened if Asia had been excluded. Should Asiaās growth and poverty trends continue, the region will be free of extreme poverty3 by 2025. Yet many will argue that, for Asia and the Pacific, the $1.25 poverty line is inadequate; it underestimates the minimal costs actually faced by the poor. This special chapter examines several critical aspects that are not captured by the $1.25 poverty line and that could have significant implications for poverty assessment in the region.
In 1981, 1.59 billion Asians were poorāa poverty rate4 of 69.8% (Figure 1.1). In 1990, the number of poor had fallen to 1.48 billion peopleāor a 54.7% poverty rate. By 2005, Asia had succeeded in halving extreme povertyāits 26.9% rate just below half the 1990 level. That beats the 2015 MDG target deadline by a decade.

For the developing world as a whole, the poverty rate fell from 43.1% in 1990 to 25.1% in 2005 and to 20.6% in 2010. This met the MDG global target (Figure 1.2). However, excluding Asia, the extreme poverty rate would have been 24.9% in 1990 and 20.5% in 2010; meaning the rest of the developing world would not be able to halve its 1990 poverty rate until after 2030.

Box 1.1: Poverty Assessment and Purchasing Power Parities
The International Comparison Program (ICP) provides internationally comparable prices or purchasing power parities (PPPs). For the 2011 round, 199 countries participated and collected price and expenditure data over a large range of final goods and services that make up gross domestic product (GDP).
PPPs are expressed as the ratio of prices in local currency of the same defined products across different counties. Their computation involves three steps: (i) for individual products, price relatives are calculated; (ii) the price relatives under each basic heading are averaged to yield unweighted PPPs; and (iii) the unweighted PPPs are then averaged to obtain final PPPs using expenditure shares of basic headings as weights (World Bank 2014a).
The first $1.08/person/day international poverty line was based on 1993 PPPs and 33 national poverty lines. The $1.25 poverty line was based on 2005 PPPs and 74 national poverty lines. Although the 2011 PPPs were released in May 2014, these will not be used to update the international poverty line until a large number of national poverty lines are updated. The World Bank is reported to have begun the process of updating the international poverty lineāwhich could take some time, judging from past experience.
By magnitude, from 1990 to 2010 the number of extremely poor declined by 745.42 million in Asiaāas against 693.47 million globally. This means the number of extremely poor actually increased across the rest of the developing world (by 51.95 million), partly due to population growth. Asia also stands out if the āmoderate povertyā line of $2/day/person is used. Between 1990 and 2010, the number of moderately poor declined by 566.31 million in Asia, while increasing by 97.73 million in other regions.
Within Asia, poverty reduction has varied across subregions and by economy. It has done best by far in East Asiaāled by the Peopleās Republic of China (PRC), the worldās most populous country. Over a 20-year period, extreme poverty in East Asia fell from about 60.2% in 1990 to 11.6% in 2010āwith the PRC reducing the number of extremely poor by 527.64 million. By contrast, India, the second most populous country, reduced its extremely poor by 48.26 million.
The level of extreme poverty in developing Asia will very likely continue to decline significantly. As presented in Section 5, the extreme poverty rate for the region is projected to decline from 20.7% in 2010 to 12.7% in 2015, 5.8% in 2020 and about 2.5% in 2025. Using World Bank criterion, this means extreme poverty will be technically āeradicatedā by 2025. These projections support other studies.5
