COD-PS Required Characteristics (minimum requirements in red)

Metadata

Source organization must be clearly identified, and acceptable for humanitarian use
Population data are endorsed by IM Network
Dataset must be able to be shared (at least once at the onset stage of an emergency)
P-codes from COD-PS match COD-AB (tables can link 1:1)

Tabular Attributes

Field names are clear and understandable
Field names used consistently across all Admin layers
Population breakdown exists for sex and age for each administrative unit (with sex disaggregation for every age cohort)
All values must be integers.
All values must be present
Sum of data matches the value of higher admin level
Data is checked for inconsistencies
Data is checked for outliers
P-codes are the unique identifiers used in the country (ideally government sourced)
P-codes are present and unique for each administrative unit
P-code attribution is consistent across all layers
P-codes for higher level administrative units are included in lower levels
P-codes and feature names (and therefore feature counts) should conform to established and accepted administrative boundary datasets (COD-AB) - however, it may be that the COD-PS is the more reliable authority.

Identify (possibly additional) partners in your IM Network who are 'experts' in population statistics/demographic data. UNFPA should be included as defined by Joint letter regarding cooperation between UNFPA and OCHA on CODs
Identify population datasets for a country that are available at different administrative levels and ideally age and sex-disaggregated. They need to match the COD-AB and should be identified and processed at the same time.
If datasets require processing to improve them (e.g. projectionsestimations, SADD, etc) the methodology should agree to by the IM network and include in the metadata. This should be done during preparedness activities as it is expected that within 48 hours of an event triggering a humanitarian emergency,
Gain endorsement by the IM Network that the dataset is the COD-PS
Gain endorsement by the HC/RC of the COD-PS
the COD-PS dataset and metadata should be widely shared through national, regional and global channels (HDX) to support data compatibility pertaining to the emergency.
