Organization Units (OU) specifies the location or where REACH indicators are collected, analyzed, or presented on a dashboard.
There are two main types of OUs in the data hub:
- Test World - a list of OUs for development and testing objects in the data hub. This is where we have been doing our practices.
- REACH World - a list of OUs for production or real use in the data hub.

OU Tree
The OUs are structured in the form of a tree or through a hierarchy to allow entries, data processing, different levels for reporting, presentation of REACH data, and drill-downs/ups on the dashboards. They also define access levels in the data hub.
REACH Data Hub OUs are grouped into OU groups and group sets for disaggregation of REACH indicators data. The structure is in the form hierarchy and begins with the country to subnational level 4.
| Country | Subnational Level 1 | Subnational Level 2 | Subnational Level 3 | Subnational Level 4 |
|---|---|---|---|---|
| Kenya | County | Sub-county | Ward | Facility |
| Ghana | Region | District | Sub-district | Facility |
| Mali | Region | District | Aire de santé | Facility |
| Sierra Leone | Province | District | Chiefdom | Facility |
| Zambia | Province | District | Facility | / |
