Example response

A real response from this endpoint. Rows are returned under "data", and provenance is carried in the shape shown below — it is not identical across datasets, so read this page's rather than assuming another's.

Chinese data values are shown as a marker here so this page stays in English; the /zh page shows them verbatim.

Provenance

These columns are returned alongside the data and record where the row came from. They are provenance, not the dataset's subject matter, so they are listed here rather than in the field table.
