For country-level spending, two different precision codes exist within the UCDP-AidData Codebook:
- Precision 6:“The location can only be related to an independent political entity, meaning the pair of coordinates that represent a country. This includes aid that is intended for country-wide projects as well as larger areas that cannot be geo-referenced at a more precise level.”
- Precision 7:“Unclear. The country coordinates are entered to reflect that sub-country information is unavailable.”
For ADM1 level spending (sub-national regional spending) no equivalent set of precision codes exists. This is difficult for some of programs which work entirely within one specific sub-national region but which may not be able to provide sub-ADM1 geocoding information. For instance, under the existing UCDP-AidData code list an activity spending 100% of its money on technical support to the regional government of the Northern Region of Ghana and a field-level program working in many districts in the Northern Region of Ghana but without the capacity to georeference its activities at the ADM2 level would both be geocoded identically. However, the actual precision of the geographic specificity would be quite different.
