We are used to thinking about inequality within countries--about rich Americans versus poor Americans, for instance. But what about inequality between all citizens of the world? Worlds Apart addresses just how to measure global inequality among individuals, and shows that inequality is shaped by complex forces often working in different directions. Branko Milanovic, a top World Bank economist, analyzes income distribution worldwide using, for the first time, household survey data from more than 100 countries. He evenhandedly explains the main approaches to the problem, offers a more accurate way of measuring inequality among individuals, and discusses the relevant policies of first-world countries and nongovernmental organizations.

Inequality has increased between nations over the last half century (richer countries have generally grown faster than poorer countries). And yet the two most populous nations, China and India, have also grown fast. But over the past two decades inequality within countries has increased. As complex as reconciling these three data trends may be, it is clear: the inequality between the world's individuals is staggering. At the turn of the twenty-first century, the richest 5 percent of people receive one-third of total global income, as much as the poorest 80 percent. While a few poor countries are catching up with the rich world, the differences between the richest and poorest individuals around the globe are huge and likely growing.

REVIEWS

"Don't be fooled by globalization's noisy naysayers or proponents, who invoke the rise or decline of 'global inequality' to make their case. Here, in the first comprehensive look at inequality across the world's individuals as well as the world's nations, are laid out the many definitions of global inequality, and comprehensive, evidence-based analysis about the course of global inequality, variously defined, before and during our globalization era."
—Nancy Birdsall, founding President of the Center for Global Development

"Branko Milanovic's painstaking work takes us closest to a global understanding of income disparities at the present time. Among many other things, his work underscores that while national level income disparities are often obscene, international differences account for much more of the even more obscene level of global income inequality."
—Jomo K. S., Assistant Secretary General for Economic Development, United Nations

"Worlds Apart is a real tour de force. It presents a new interpretation of trends in the distribution of income among the world's countries and individuals, and makes a strong argument that global income inequality can be and should be reduced. In this emerging issue area of international politics it will become a standard reference."
—Robert Hunter Wade, London School of Economics

"A fascinating read. This book is a helpful primer to help you find your way around the complex debates surrounding global inequality. It is also a forceful demonstration that the world economy remains much too unequal."
—Dani Rodrik, Harvard University

"An important book by a master of the relevant data. Milanovic provides hard answers to tough questions."
—Samuel Bowles, Santa Fe Institute, author of Microeconomics: Behavior, Institutions, and Evolution
