The following applies to all of the information in the EarthTrends database, unless noted otherwise. For specific information on a particular variable, please refer to the Sources and Technical Notes.
• “..” in a data column signifies that data are not available or are not relevant (for example, country status has changed, as with the former Soviet republics)
• "0" indicates a value of either zero, less than one-half the unit of measure used in the table, or greater than negative one-half the unit of measure used in the table.
• Except where identified by a footnote, regional totals are calculated using regions designated by the World Resources Institute. Totals represent either a summation or a weighted average of available data. Weighted averages of ratios use the denominator of the ratio as the weight. Regional totals are published only if more than 85% of the relevant cases are available for a particular region, with regional totals for measures of GDP shown only if 95% of the population are represented by the available data. Missing values are not imputed. Regional totals use data from all 222 countries and territories in the World Resources/EarthTrends database.
• Except where identified with a footnote, world totals are presented as calculated by the original data source (which may include countries not listed in WRI’s database); original sources are listed after each data table.
Regional Groupings of Countries
Country groupings are based on lists developed by the Food and Agriculture Organization
of the United Nations (developed and developing countries), the World Bank (high-,
medium-, and low-income countries), and the World Resources Institute (regional
classifications).
