A poverty line helps focus the attention of governments and civil society on the living conditions of the poor. This paper offers a critical overview of alternative approaches to setting poverty lines. In reviewing the methods found in practice, the paper tries to throw light on, and go some way toward resolving, ongoing debates about poverty measurement, emphasizing those debates which would appear to have greatest bearing on policy discussions.

This book is an introduction to the theory and practice of poverty measurement. On completing this book you will be able to perform sophisticated analyses of income or consumption distribution for any standard household dataset using the ADePT program (a free download from the World Bank s website).

The final book from a towering pioneer in the study of poverty and inequality—a critically important examination of poverty around the world In this, his final book, economist Anthony Atkinson, one of the world’s great social scientists and a pioneer in the study of poverty and inequality, offers an inspiring analysis of a central question: What is poverty and how much of it is there around the globe? The persistence of poverty—in rich and poor countries alike—is one of the most serious problems facing humanity. Better measurement of poverty is essential for raising awareness, motivating action, designing good policy, gauging progress, and holding political leaders accountable for meeting targets. To help make this possible, Atkinson provides a critically important examination of how poverty is—and should be—measured. Bringing together evidence about the nature and extent of poverty across the world and including case studies of sixty countries, Atkinson addresses both financial poverty and other indicators of deprivation. He starts from first principles about the meaning of poverty, translates these into concrete measures, and analyzes the data to which the measures can be applied. Crucially, he integrates international organizations’ measurements of poverty with countries’ own national analyses. Atkinson died before he was able to complete the book, but at his request it was edited for publication by two of his colleagues, John Micklewright and Andrea Brandolini. In addition, François Bourguignon and Nicholas Stern provide afterwords that address key issues from the unfinished chapters: how poverty relates to growth, inequality, and climate change. The result is an essential contribution to efforts to alleviate poverty around the world.

Understanding poverty and what to do about it, is perhaps the central concern of all of economics. Yet the lay public almost never gets to hear what leading professional economists have to say about it. This volume brings together twenty-eight essays by some of the world leaders in the field, who were invited to tell the lay reader about the most important things they have learnt from their research that relate to poverty. The essays cover a wide array of topics: the first essay is about how poverty gets measured. The next section is about the causes of poverty and its persistence, and the ideas range from the impact of colonialism and globalization to the problems of "excessive" population growth, corruption and ethnic conflict. The next section is about policy: how should we fight poverty? The essays discuss how to get drug companies to produce more vaccines for the diseases of the poor, what we should and should not expect from micro-credit, what we should do about child labor, how to design welfare policies that work better and a host of other topics. The final section is about where the puzzles lie: what are the most important anomalies, the big gaps in the way economists think about poverty? The essays talk about the puzzling reluctance of Kenyan farmers to fertilizers, the enduring power of social relationships in economic transactions in developing countries and the need to understand where aspirations come from, and much else. Every essay is written with the aim of presenting the latest and the most sophisticated in economics without any recourse to jargon or technical language.

For anyone wanting to learn, in practical terms, how to measure, describe, monitor, evaluate, and analyze poverty, this Handbook is the place to start. It is designed to be accessible to people with a university-level background in science or the social sciences. It is an invaluable tool for policy analysts, researchers, college students, and government officials working on policy issues related to poverty and inequality.

In 2013, the World Bank Group announced two goals that would guide its operations worldwide. First is the eradication of chronic extreme poverty bringing the number of extremely poor people, defined as those living on less than 1.25 purchasing power parity (PPP)†“adjusted dollars a day, to less than 3 percent of the world’s population by 2030.The second is the boosting of shared prosperity, defined as promoting the growth of per capita real income of the poorest 40 percent of the population in each country. In 2015, United Nations member nations agreed in New York to a set of post-2015 Sustainable Development Goals (SDGs), the first and foremost of which is the eradication of extreme poverty everywhere, in all its forms. Both the language and the spirit of the SDG objective reflect the growing acceptance of the idea that poverty is a multidimensional concept that reflects multiple deprivations in various aspects of well-being. That said, there is much less agreement on the best ways in which those deprivations should be measured, and on whether or how information on them should be aggregated. Monitoring Global Poverty: Report of the Commission on Global Poverty advises the World Bank on the measurement and monitoring of global poverty in two areas: What should be the interpretation of the definition of extreme poverty, set in 2015 in PPP-adjusted dollars a day per person? What choices should the Bank make regarding complementary monetary and nonmonetary poverty measures to be tracked and made available to policy makers? The World Bank plays an important role in shaping the global debate on combating poverty, and the indicators and data that the Bank collates and makes available shape opinion and actual policies in client countries, and, to a certain extent, in all countries. How we answer the above questions can therefore have a major influence on the global economy.

Poverty comparisons - such as whether poverty has increased, or where it is greatest, are typically clouded in conceptual and methodological uncertainties. How should individual well-being be assessed in deciding who is poor? Is a household survey a reliable guide? Where should the poverty line be drawn, and does the choice matter? This monograph surveys the issues that need to be considered in answering these questions, providing an accessible introduction to the most recent literature. The strengths and weaknesses of past methods are discussed, and a summary of methodological recommendations is given. A number of new analytical tools are described which can greatly facilitate poverty comparisons, recognising the uncertainties involved.
