data availability and representativeness
I am writing to ask you the following questions:
1) I know that your data is available/can be decomposed at by UK regions. Do you have information decomposed by the 650 parliament constituencies in the UK? If yes, is this data available?
2) Is your data representative at the region level?
3) Is your data representative at the constituency level?

Technically we represent all subgroups of the population - some may be too small for a good representation and some may be just too small to even be in the dataset (e.g. one postcode or an extremely rare illness). With any rare events or subgroups one just need to look at the data and get confidence interval around their estimates to see whether the sample size is sufficient for their purpose.
