Annual gross amount of water extracted from rivers, lakes and reservoirs.

Water occurring on the earth’s surface in glaciers, lakes and rivers (i.e. surface water), and underground in aquifers (i.e. groundwater). Its key factor is a low concentration of dissolved salts.

Total freshwater withdrawn in a given year, expressed in percentage of the total renewable water resources (TRWR). This parameter is an indication of the pressure on the renewable water resources.

The frozen frame is a subset of the snapshot that comprises all statistical units that are active, or potentially active, or active within the previous reference year. It also includes administrative units that are linked to these statistical units. The aim is to include all units and all characteristics that are used by subsequent processes. In other words it is a trimmed down version of the snapshot that is easier to manipulate because the possible large number of inactive units are not there. It may be further restricted by containing only units for which there are values for the characteristics that are to be used for frame extraction and sample selection for at least one survey.
