Finding and recording a series
The indicators portal links the underlying releases and SIDRA tables. Record a table identifier, geography, time period and unit instead of citing only a headline indicator.
When a download is offered, retain the file alongside the table metadata. Check the publisher's current export options and licence; this page does not promise a particular format or API.
