SDR is the age-standardized death rate calculated using the direct method and standard European population structure.
CDR is the crude death rate calculated as a simple ratio: number of registered deaths/ mid-year population (per 100000).

Mortality rates have been calculated by the WHO Regional Office for Europe using the data on deaths by cause/age/sex and mid-year population by age/sex, annually reported to WHO by European Member States. It should be noted that Mortality rates for some countries may be biased due to the under-registration of death cases, particularly in the central Asian republics, the Caucasus countries and some countries in the Balkans region (seenotes on data availability and quality under menu item Help).
