To ask the Secretary of State for Health what research his Department has carried out on the geographical distribution of people with (a) type 1 and (b) type 2 diabetes to enable effective allocation of resources for treatment to take place. 
The Department has not carried out any such research. It is for national health service organisations to commission diabetes services that meet the needs of their local populations and allocate to resources appropriately.
The Yorkshire and Humber Public Health Observatory has published the PBS Phase 3 Diabetes Prevalence Model, which provides diabetes prevalence estimates for all areas of England. This tool is available to the NHS to support them to undertake a needs assessment in their area and plan services accordingly.
To ask the Secretary of State for Health how many children under the age of 16 years in (a) Hemel Hempstead constituency and (b) Hertfordshire have type 1 diabetes. 
Data on the number of children under the age of 16 years with diabetes in Hemel Hempstead and Hertfordshire are not collected centrally.
At a national level, exact figures for the number of children diagnosed with and treated for diabetes are not available.
