China Area Data

China Area Data is a structured dataset containing administrative division information for China. It organizes provinces, municipalities, cities, districts, counties, and related regional identifiers into formats suitable for software applications. The package can be installed through npm and used directly in JavaScript projects. Multiple data layouts are provided, including object-based JSON, array-based JSON, and JavaScript representations. Versioned datasets preserve older administrative structures so applications can account for regional code changes over time. The latest included major dataset is based primarily on National Bureau of Statistics information from 2019 and also includes Taiwan, Hong Kong, and Macau entries.
