Confidence limits around prevalenceat different levels of analysis
Proportion of areas with obesity prevalence significantly different (higher/lower) to England
Methods for increasing robustness of NCMP analysis for small populations • Combine NCMP data from different years • example: NOO MSOA e-atlas • Combine small geographic areas into larger population groups/ neighbourhoods • example: combine 5 MSOAs into neighbourhood • Combine populations with similar characteristics • example: ONS Area Classification
