Problem
The database contained duplicate state records with the same
nameandcountry_codebut different types (e.g., "county" vs "city", "region" vs "municipality"). This caused data inconsistencies and confusion when querying geographical data.The issue identified 15 specific duplicate state IDs that needed to be removed:
738, 5140, 5146, 5149, 5165, 5183, 5191, 5198, 5203, 5204, 5327, 5328, 5336, 3418, 3423Additionally, during analysis, one more duplicate was found:
5144(Bayamón PR)These duplicates were affecting 29 cities (30 including Bayamón) that needed to be reassigned to their correct parent states.
