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.

Considerations

...

  • Leaving no one off the map A gridded population data report from a  wide range of experts : Key messages: 1) census data are still important, gridded population data are not a substitute for census data; 2) gridded population data are not error-free; 3) data users should consider a number of factors when selecting an appropriate dataset for their particular needs; 4) more validation work is needed to compare gridded population data estimates against authoritative data on population location.
