This website uses public statistical data published through the National Bureau of Statistics of China's official data platform, 国家数据 (National Data). The platform provides access to a wide range of official indicators, including monthly, quarterly, annual, census, regional, departmental, and international datasets. This site turns those official figures into clearer, easier-to-explore visual charts.

The goal of this website is not to replace the National Bureau of Statistics source, but to make a small part of it more accessible. The official database is broad and information-dense, while this website narrows the experience to a few key demographic indicators and presents them in a format that makes province-level comparison easier. Users can review trends over time, compare regions against the national aggregate, and move between related topics through a more focused interface.

All featured statistics are derived from official data released by the National Bureau of Statistics of China. The source platform includes structured data categories such as annual data, regional data, census data, and statistical publications, which makes it a reliable foundation for this kind of exploratory dashboard. This website uses those published figures as the basis for its charts and summaries, while the interpretation, layout, and interaction design are original to this website.

For users who want to verify figures or explore beyond the scope of this website, the original source remains the best reference point. The National Data platform includes direct access to broader statistical collections, additional indicators, and official publications. This website should be understood as a guided interface built on top of official public statistics, designed to help users explore selected trends more quickly.
