Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, pursuant to the Answer of 20 March 2025 to Question 37767 on GP Practice Lists, what weighting does the Carr-Hill Formula give to patient deprivation.

The Carr-Hill formula does not include a weighting for patient deprivation. Amongst the range of factors included in the formula, the proportion of the population with a limiting long-term illness (LLTI) and the standardised mortality ratio (SMR) for those aged under 65 years old (SMR<65) are correlated with higher deprivation. The weightings for these factors are the practice list multiplied by (48.1198 + (0.26115 multiplied by the practice’s LLTI) + (0.23676 multiplied by the practice’s SMR<65)).
