Database Structure

The IDL is structured according to the country of death of the individuals or, in case the individual is still alive, to the country of current residence. If known, the country of birth is also listed. For each country, information on the data collection process is given in the meta-data. It is essential to take this information into consideration when performing demographic analyses.
The following information is provided for each individual:
ID This numeric identifier is introduced to trace individual information in the original data sources if errors are reported to the IDL.
Age (years) Age in completed years (either age at death or age when last recorded alive)
Age (days) Age in days (either age at death or age when last recorded alive)
Sex Sex of the individual (F=female, M=male)
Country of Birth
Date of Birth
Date of Death if the individual is deceased
Date Alive if the individual was still alive while the data was collected
Country of Death if the individual is deceased
Country of Residence if the individual was still alive while the data was collected
Validation validation status (for further information click here)

This information can be sorted in ascending/descending order by clicking on the column headers.

Meta-data

The meta-data contain information on the original data sources and the data collection process. This includes information on the selected birth cohorts, the age-range of the data, whether information on deaths and/or information on people alive was collected, and the time-window in which the information was sampled. Information on the validation procedure is given, as is country-specific information, when available.
