On average, there are 1,719 patients for every full-time-equivalent GP in England.
The figures, a snapshot from August 31 of this year, were published by NHS Digital.
The GP-to-patient ratio is only one way of looking at how busy a surgery is.
Most surgeries will also have other staff treating patients, such as nurses, physiotherapists and midwives.
Sometimes, a surgery might appear to have a low number of GPs because they share staff with a neighbouring practice. Alternatively, they may have been in the process of recruiting when they supplied their staffing figures to the NHS.
