  1. noo National Obesity Observatory Local area analysis using NCMP data Caroline Ridler & Kath Roberts

  2. Guidance for small area analysis http://www.noo.org.uk/NCMP/analytical_guidance

  3. Confidence limits around prevalenceat different levels of analysis

  4. Proportion of areas with obesity prevalence significantly different (higher/lower) to England

  5. 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

  6. MSOA e-atlas

  7. Combining MSOAs into neighbourhoods

  8. ONS Area Classification
