Why is building an Administrative Divisions Database complex?

The complexity arises from inconsistent global standards, frequent boundary changes, non-uniform naming conventions (e.g., “suburb” in Australia vs. “county” in the US), and variations in administrative levels across countries. Integrating and harmonizing data from multiple sources requires advanced normalization, versioning, and geospatial validation techniques.
