ONS Postcode Refresh


Every year our database is refreshed with the latest postcodes and updated boundary areas from the Office for National Statistics (ONS). All newly published annual datasets will reference the new ONS data for Geography reports in the Observatory.

What will happen to historic Geography reports?
History is frozen so historical datasets will reference the ONS data that was current in the year the dataset was published to the Observatory. Please take this into account if you compare a current annual dataset to a dataset from a previous year and be sure that it is made clear in any geographic information you report.

Is there anything I need to do?
No, the new annual dataset will get automatically appended with the new ONS data when it is first published to the Observatory.
