Changed
- The census catalogue on GET /v1/census/catalog/{datasetCode} lists only categories served in the requested dataset, and each entry's
availableGeotypesreflects the levels actually served, so the geography levels you discover match what the tile, break and value endpoints return. - Every served variable now carries a normalised theme in
variableGroup, drawn from one vocabulary (population,education,identity,housing,health,work) that is consistent across nations, so England and Wales and Scotland variables group the same way.
Fixed
- Variable discovery on GET /v1/census/datasets/{datasetCode}/variables and lookup on GET /v1/census/datasets/{datasetCode}/variables/{slug} return only variables with at least one served geography level in the dataset. Read
availableGeotypesto decide which levels to request.
