When viewing an image of a record from the 1921 Census of England and Wales or the 1939 Register there is an icon in the Options menu that says ‘Toggle transcript pop-up' when you hover over it. Select this to turn the feature off, and again to switch it back on.
Transcript pop-ups will only be available on 1921 Census records when both the transcript and the image of the same record have been purchased. Note this feature is only available for larger screen sizes, such as desktop computers.
We have worked with a trusted transcription house on numerous projects for several years. When transcription of the 1921 Census took place, each digital image had to be broken up into segments so that the person transcribing it could not see a whole record or household. This was to ensure we complied with security and data protection regulations but also why you might see various spellings of the same surname or street address on one record because it has been transcribed by multiple people without the context of the whole record
Our aim when working on the transcription of the 1921 Census was to deliver a 98.5% accuracy rate across the 38 million individual records and from our initial quality control we believe we have achieved this. However, due to the secure nature of the 1921 Census project, the period of time in which we have been able to access and review the data ahead of launch has been limited and we have been unable to conduct the same level of quality assurance checks we would normally apply to such a major release.
To ensure the highest possible transcription standards we will be continually reviewing the data to correct any and all errors over time.
