Common questions

How is data calculated for areas based on postcodes?

All indicators in Local Insight are based upon statistical geographies; Output Area (OA), Lower layer Super Output Area (LSOA) and Middle layer Super Output Area (MSOA). In order to calculate data for custom areas based on postcodes, Local Insight identifies all the OAs covered by the uploaded postcodes and then sums the data for the combined OAs. Please note that weighting is not applied if multiple postcodes are uploaded which reside within the same OA. Each OA covered by the uploaded postcodes will have equal weighting when data is calculated.
