This book is based on the World Development Indicators 2001 and its accompanying CD-ROM. Under the headings of agriculture, forests, biodiversity, energy, emissions and pollution, water and sanitation, and 'greener' national accounts, it presents key indicators of the environment and its relationship to people for more than 200 countries. The data in this book are for the most recent year available between 1997 and 2000, unless otherwise noted. Regional data include only low- and middle-income economies. Aggregates for regions and income groups are shown only if data are available for 66 percent of the economies in that group. Countries included have populations of more than 30,000 or are World Bank members.
