Resource information
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.
