Malawi administrative level 0-3 shapefiles, geodatabase, gazetteer, and geoservices P-codes are based on the NSO Admin 3 code system. In the administrative level 3 feature names, "STA" stands for "Senior Traditional Authority" and "TA" stands for "Traditional Authority". These shapefiles are suitable for database or ArcGIS linkage to the [Malawi - Subnational Population Statistics](https://data.humdata.org/dataset/cod-ps-mwi) tables.
