'OVERVIEW' matrix:
Four doughnut charts provide a country overview by status ('Operational' or 'Preparedness') and COD type ('Administrative Boundaries' or 'Population Statistics'). Each doughnut chart depicts:
- Green segment: number of countries with at least one 'fully usable' administrative level
- Orange segment: number of countries with no 'fully usable' administrative levels but at least one 'partly usable' administrative level
- Red segment: number of countries with no 'fully usable' or 'partly usable' administrative levels but at least one 'needs improvement' administrative level
- Grey segment: only 'not evaluated' administrative levels. These refer to countries where there is only a COD of the other status ('Operational' or 'Preparedness')

Evaluation criteria
COD-ABs and COD-PSs are evaluated by FIS according to established criteria to maintain standardized levels of quality. Field IMOs are encouraged to use the same criteria for evaluation of candidate CODs and for periodic review of published CODs.
Each administrative level (except level 0 and any level below level 4) is evaluated individually, although some criteria apply to entire COD-AB datasets (comprising multiple administrative levels). The evaluated levels are:
- Fully usable: The COD can be used for any purpose
- Partly usable: The COD has some problems that may limit its use (see below)
- For administrative boundary CODs this means that not all of the spatial criteria are satisfied
- For population statistics CODs this means that the sex and age disaggregation is incomplete
- Needs improvement: The COD is only useful for very limited purposes
Criteria are grouped. Each group has a rule for designation as 'Fully usable', 'Partly usable', or 'Needs improvement'. The evaluation of the entire administrative level is equal to the worst group evaluation.
Country statistics depend on the evaluation of the worst administrative level in the COD dataset.
Some COD-AB and COD-PS criteria are applicable to the entire COD-AB (an HDX 'dataset') or to the individual administrative layer. Evaluations for entire datasets are assigned to every component administrative layer.

Exceptions may be made. For instance, the Bangladesh COD-AB features layers with and without inland waters.
Equivalent files should not be found elsewhere on HDX.
