E.11 Analysis was also carried out at LCG level, to determine how percentage shares for each LCG would vary using either NI-PU or the relevant STAR-PU. Table E.3 shows how resources are redistributed across LCGs using age gender weightings compared to crude population shares. If resources for cardiovascular medicines were being shared out, the use of NI-PU would only redistribute +/- 1.95% of resources, whereas the use of a BNF 2 STAR-PU would redistribute +/- 3.25% of resources.

The shares for the other three LCGs decrease when NI-PU is applied to their crude population shares, as they have younger age profiles.
