CSO Frontier Series may use new methods which are under development and / or data sources which may be incomplete, for example new administrative data sources.

Publishing outputs under the Frontier Series allows the CSO to provide useful new information to users and get informed feedback on these new methods and outputs whilst at the same time making sure that the limitations are well explained and understood.

The data supporting these release formats may be published on the CSO’s PxStat database or as Excel files.
