Ethnicity was collected by most LPS, but to varying degrees of granularity. UK LLC has harmonised LPS data on ethnicity into six, five and two categories to include all LPS that collected these data. Only the most and least granular categories are presented here.
For NHS England, a hierarchy of source reliability established by the British Heart Foundation Data Science Centre was used (https://www.bmj.com/content/373/bmj.n826). Where multiple entries existed from the preferred source, the most recent was given precedence.
