Data access guide

The Data Access Guide does not cover how to access data via the UKB Research Analysis Platform (RAP); see here for information about using the RAP.

Please see the Understanding UK Biobank page for information about the data available, which also includes further information and reports about linkage data (Cancer, Hospital Inpatient, Death).

Data Dictionaries and Encodings

  Data Dictionary of Showcase fields:   List of Data-Codings (including those for the Data Portal): The comma-separated values (csv) versions of the above are easier to view in packages such as Excel, however as the field descriptions and coding meanings sometime contain commas some of the fields are enclosed in quotes to indicate such a comma is not a separator. The tab-separated values (tsv) versions are therefore provided as an alternative.

UKB Synthetic Dataset

A synthetic version of the UK Biobank dataset has been created to allow large scale system testing using data which is comparable in size and constitution to the real dataset.
