High Resolution Population Data for Humanitarian Operations is pending successful nomination. Areas to be addressed include:

• To adopt a catchier project name that is specific and less generic than the current one.
• Secondly, considering UNICEF is listed as the organization owner for this project, it would represent the interests of the organization better to host this repo under UNICEF GitHub organization versus using an individual GitHub account.

@lacabra therefore technical review of the full submission will be put on hold until the project has passed the nomination stage.

Digital solutions that are no longer active, or do not provide the required documentation needed for review, will be moved into the archive hence moving High Resolution Population Data for Humanitarian Operations to archives as per the archiving policy. Thanks.
