In 1872 sanitary districts were established, giving public health and local government responsibilities for rural areas to the existing boards of guardians of poor law unions.
The Aylesbury Rural Sanitary District therefore covered the area of the poor law union except for Aylesbury itself, which had a local board of health and so formed its own urban sanitary district.
In 1933 the county boundary with Oxfordshire was adjusted, and the parish of Kingsey was added to Buckinghamshire and to Aylesbury Rural District.
