This data was originally published in the reports of the Registrar-General for England and Wales. It was computerised by the Great Britain Historical GIS Project and its collaborators. It forms part of the Great Britain Historical Database, which contains a wide range of geographically-located statistics, selected to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain, generally at sub-county scales.

In this period, 1911 to 1973, the main reporting units were over 1,500 local government districts, as compared to c. 600 Registration Districts pre-1911. As a result, most tabulations provide data only for the larger urban units, plus aggregates covering all Rural Districts and all other urban units in each county. This study centers on the main exception to this, an annual table providing counts of all births, all deaths and all infant deaths in all districts, appearing in the Registrar-General's Annual Reports from 1911 to 1920, then in the RG's Statistical Reviews from 1921 to 1973. Later reports include additional variables. This study also includes more limited transcriptions of causes of death and age-specific mortality.

The Great Britain Historical Database has been assembled as part of the ongoing Great Britain Historical GIS Project. The project aims to trace the emergence of the north-south divide in Britain and to provide a synoptic view of the human geography of Britain at sub-county scales. Further information about the project is available on A Vision of Britain webpages, where users can browse the database's documentation system online.

The British census reports generally cross-tabulated age against marital status as well as gender, but the transcriptions in the Great Britain Historical Database are generally limited to age and gender, enabling the construction of population pyramids. This dataset is a quite separate transcription limited to marital status, or "conjugal condition", and gender, held only for Scotland in 1931.
