• Number of records
• Spatial relationship of records
• Distribution of records

The analysis was taken at a national level for England, Scotland and Wales, using predominantly the same method, although for England there was a slight variation to obtain the average distance to centroid. In this case, the analysis was undertaken at 9 regional levels and then an average of the averages taken due to processing power needed.

Methodology

• Review UPRNs and distance to centroid of postcode
• Remove those UPRNs not in the same polygon spatially – for a variety of reasons
• Exclude multipart polygons from analysis as skew the results
• Exclude vertical streets

The resulting analysis demonstrated that UPRNs offer more granular and accurate analysis than postcodes.
