Species diversity is a measure of the diversity within an ecological community that incorporates both species richness (the number of species in a community) and the evenness of species' abundances. Species diversity is one component of the concept of biodiversity.
The trade surplus or deficit of material resources within an economy, calculated as imports minus exports of raw materials and manufactured products.
The Environmental Vulnerability Index is a measure to characterize the relative severity of various types of environmental issues suffered by individual nations and some regions of the planet.
The Wildlife Picture Index (WPI) combines photos from camera traps and relevant environmental data to understand how well efforts to protect biodiversity are functioning. It was designed to address the need for robust biodiversity monitoring indicators to fulfill the Convention on Biological Diversity’s goal to reduce the rate of biodiversity loss by 2020.
Crop production index shows agricultural production for each year relative to the base period 2004-2006. It includes all crops except fodder crops.
"Total population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship - except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. The values shown are midyear estimates."

Population density of a country is midyear population divided by land area in square kilometers. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship--except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of their country of origin. Land area is a country's total area, excluding area under inland water bodies, national claims to continental shelf, and exclusive economic zones.
The Resource efficiency scoreboard is a tool / user interface for presenting key indicators relating to natural resources. For this scoreboard, a limited set of already available indicators was selected, covering as many as possible of the themes and subthemes identified in the Roadmap to a resource efficient Europe. It is a three tier system based on a lead indicator, a dashboard of indicators and a set of theme specific indicators:
- One Lead indicator – focus on resource productivity
- 9 Dashboard indicators with focus on carbon, water and land;
The indicator is an aggregated index integrating the population abundance and the diversity of a selection of common bird species. Three groups of bird species are presented in this indicator: farmland specialists (39 species), forest specialists (33 species) and all common bird species (farmland species, forest species and a further 91 species).Rare species are excluded.
