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.

Frequently Asked Questions
The American Samoa is divided into 3 districts and 2 atolls, which form the top-level administrative units. These are further divided into 16 counties. Major districts include Eastern, Manu’a, and Rose Atoll.
The American Samoa has 2 administrative levels. Level 1: 3 districts and 2 atolls. Level 2: 16 counties.
American Samoa operates on a 3‑level system starting with 5 districts, then counties, and villages as the smallest administrative units.
In the American Samoa, districts and atolls both sit at administrative level 1 but serve different functions. Districts — there are 3 — typically group multiple smaller municipalities under a shared administration. Atolls — there are 2 — are a larger city or urban area that handle its own administration independently.
Administrative boundaries in the American Samoa change as governments reorganize regions, merge municipalities, or create new administrative units to reflect population shifts and political decisions. Changes most commonly affect the counties level, where the American Samoa currently has 16 units. Businesses that rely on American Samoa administrative data should use a regularly updated reference dataset to avoid mismatches in geocoding, tax jurisdiction mapping, and compliance reporting.
